Abstract
It is disclosed here a Tesla equipment modified by the partial or total replacement of its smooth discs by discs called Tesla-Pelton discs (1').
The discs disclosed here, present the characteristics of the Pelton wheel, once it has veins (11) that are hit by the working fluid. Thus, the Tesla-Pelton discs (1') increase the torque efficiency provided by the Tesla turbine. When working as a pump or as a compressor, the device presents higher efficiency in pumping or compressing due to the presence of said veins. When working as a turbine, the Tesla-Pelton device disclosed here is useful for applications that demand high torque as for example electrical generators, high speed drill machines, automotive vehicles, planes, centrifuges and others. The Tesla-Pelton device can comprises the combination of said particular discs and other kinds of discs, for example, smooth discs such as the ones commonly used on a conventional Tesla equipment. The proportion between Tesla-Pelton discs (1) and other kinds of discs, is determined according to the project specifications and defines the final torque increase in turbines or the efficiency increase of fluid pumping and fluid compression.

Description
"TESLA-PELTON DEVICE AND USE OF THE SAME"
INVENTION FIELD
The invention disclosed here belongs to the field of parallel discs equipments which its functioning is dependent of the flow of a fluid as for example, the Tesla devices.
BACKGROUND
The Tesla turbine and compressor were patented in 1910 in England under number 24001 by Nikola Tesla and consist of parallel smooth discs assembled very closed to one another in a shaft. In the case of the Tesla 1o turbine, the flow of the working fluid through the discs surfaces causes the rotation of the same. This occurs due to the phenomenon of fluid adherence to the disc surface, known as "non-slipping" condition. The fluid adherence makes the disk reach the speed of the fluid and to turn the shaft. The shaft turns causing the production of mechanic power that can be used for any purpose.
Due to the working principle of the Tesla turbine mentioned above, the working fluid must have a pressure over the atmospheric pressure and should have a tangential incident angle in the outward disc surface. It is possible to use any pressured fluid, such as example, compressed air, steam, combustion gas, a mix of them and others. The Tesla turbine must present an exhaustion port for the fluid flow exit to the environment.
In the case of the Tesla pump or compressor, the machine is similar, but works in inverse mode. In these machines, the fluid to be pumped or compressed enters into the machine in a temperature and pressure of the environmental conditions and during its compression or pumping its physical properties are changed. During these processes, the fluid increases its temperature and changes its viscosity.
In Tesla pump or compressor, the working fluid enters into the machine near the centre of the discs and is exhausted at the edge of the disk.

01. f The pumping (or compression) is obtained by turning the shaft and consequently, by the discs rotation by the machine. Differently of the Tesla turbine, the working fluid does not generate the disc rotation but it is compressed or pumping due to the discs rotation provided by the machine. The shaft can be turned by any motor or even a Tesla turbine. Thus, differently from the Tesla turbine, the Tesla pump or the Tesla compressor does not generate mechanical energy but depends on the supply of external energy to generate the mechanical energy that compress or pump the working fluid. The working fluid compression or pumping occurs due to the same fluid adhesive effect to 1o the discs surfaces, as described previously for Tesla turbine The properties of the Tesla turbine that distinguishes it from the other types of turbines and motors are: its simplicity of construction, low cost, high efficiency and ability to operate with water steam generated by any type of fuel, or any source of heat.
The Pelton wheel was developed in the mid 1880's by L. Pelton and it has been used in water falls to produce mechanical energy and after that is converted in electrical energy. It is a wheel mounted in a shaft which has blades in its edge. These blades are hit by the water falling against them, thus producing the wheel rotation and consequently, shaft rotation. Its principle of work consists in transferring the kinetic energy from the fluid to the blades by impulsion. The rotating shaft is used to run, for example, electric generators, saws, etc.
In spite of the good qualities of the Tesla turbine mentioned, there are no viable and massive commercial applications. The disadvantage of the use of Tesla turbine compared to other similar machines is the low torque.
This happens because the fluid adhesion in the disc surface is limited just of a small part of the total fluid mass. The energy of parts of the fluid mass that does not adhere to the disk surface is lost and flows directly to the exhaustion port Amended Pages 3/10 PCT Li 2 Q0 8 0 }0v6 4 without generate disk movement. Thus, the use of a Tesla turbine as a source of power to electric generators, vehicles, etc is not used, mainly because it is not efficient.
Thus it is desired developing a Tesla turbine able to generate more torque when in contact of the major part of the fluid mass flow.
The document US 2003/0053909 describes a turbine which discs comprise tridimensional blades with variable area as airfoil structures. The discs comprises airfoils with different size, wherein small airfoils are intercalated between the gap of two long airfoils. All the long airfoils extend from the edge to the centre of the disc and conduct the fluid flow to an unique opening in the centre of the disc. The presence of these airfoils turbine cause the appearance of three effects that are the shock effect of high velocity particles striking the leading surface of the airfoils, the fluid motive force of the high velocity mass flow contacting the inner walls of the disks and the lift force vector produced by the fluid flow over the airfoils. However it is questioned if this is a technically viable turbine since the lift effect makes difficult the disc rotation and the shaft opening seems to be the same of fluid exhaustion difficulting fluid exhaustion.
The document US 3,487,784 describes a heart pump that comprises means of rotation as parallels discs that comprises curved blades.
The blood flows from the centre to the edge of the disc through an opening in the center of the discs. These machines are used to pump blood for circulation through the body of an animal or a human and cannot operate with high pressure levels since the blood is a very delicate fluid that cannot be compressed or suffer any kind of injury during the pumping since it would become improper to be used. The fluid direction can also be from the edge to the centre of the disc but these machines works only at low pressure. Due to this, it could not be used as a turbine or as a high pressure pump.
Amended Pages BRIEF DESCRIPTION OF THE INVENTION
Considering 'the ;problem indicated above, it has been disclosed a.
way to increase the torque.. supplied by the original Tesla turbine. - The Tesla turbine disclosed here constitutes an invention ;that is based on the principle of working of the Pelton wheels. The discs of the Tesla turbine disclosed here present both side smooth but one of them presents veins (11). These veins (11) are three-dimensional projections in the disc surface that have elliptical shape and have constant height and thickness. These veins provide a particular surface to the impact of the part of the fluid mass that does not commonly adhere to the disk surface. Besides of this, the elliptical shape of these veins (11) conducts the fluid mass direct to the exhaustion port (9) near the centre of the disc since the exhaustion port is placed in one of the focus of this ellipse (9).
The fluid adhesive effect to the disc surface also occurs in this new disc system, such as it occurs in the smooth disc used in the original Tesla turbine (adhesive effect of the boundary layer).
Thus, in the Tesla turbine disclosed here, the increased torque is the result of the sum of the principle of fluid adhesion to the disc surface with the principle of Pelton effect of the incidence of the part of the fluid mass that does not adhere to the disc surface. Thus, it can be concluded that in such Tesla turbine, called as Tesla-Pelton turbine, the disc movement occurs due to the existence of higher torque than in the original Tesla turbine.
As the original Tesla turbine can be used as Tesla pump or Tesla compressor, the Tesla-Pelton turbine disclosed here can also works as a pump and as a compressor.
When the Tesla-Pelton device works as a pump or as a compressor, the compressing or pumping efficiency is increased due to the presence of veins in the disc surface. The operation occurs in the reverse way of the turbine, that means, the fluid to be pumped or compressed goes into the Amended Pages 5/10 c I s' / f L
V .NS ~
admission inlet near the centre of the disc (used as an exhaustion port in Tesla-Pelton turbine) and exits at the edge of the disc. The pumping (or compression) effect is obtained by turning the shaft and consequently, turning the discs, and occurs due to the sum of the two effects, that means, the adherence effect of the fluid to the discs surfaces (together with centrifugal forces, like in the Tesla pump or compressor) and the transfer of kinetic energy from the disc to the working fluid, since the concavities pushes the fluid. The spin of the shaft can be obtained by using any motor or even a Tesla turbine.
Since the Tesla-Pelton device disclosed here has higher torque than the original Tesla device, it can be used in equipments that demand high torque as electric generators, high speed drill machines, automotive vehicles, planes, centrifuges, other kinds of machine and combinations thereof.
These and other objects of the present invention will be best exemplified and described in the Figures Description sections and Invention Disclosure Sections.

Figure 2 shows the frontal view of the original Tesla turbine and the spiral path (8) that the working fluid goes along on the face of the smooth disc (1) used in the original Tesla turbine.

The disc (1), used in the Tesla turbine, has two lo smooth faces and is fixed in a shaft (2).
Figure 3. presents three Tesla-Pelton type discs assembled in the same way that they would be in the turbine shaft. On a smooth surface (1') each disc present veins (11). It should be noted that each vein (11) comprises one exhaustion port (9). However, the number of veins/exhaustion port is variable according to the project and the disc aspects. The shaft is placed by the opening in the center of the disc (12).
Figure 4 shows the smooth side (1') of three Tesla-Pelton discs assembled together. As shown in figure 4, joining the side of the Tesla-Pelton disc, which have veins (11), and the smooth side of the other Tesla-Pelton disc, the cavities of the veins become some ducts (3) through which the working fluid enters and goes through, from the edge of the disc to the exhaustion ports (9), near the centre of the disc. The fluid flow which goes into the discs surfaces pushes the veins (11) before going out by the exhaustion port (9). It is the same situation that occurs when a water flow hits on the blades of a Pelton wheel.

The Tesla-Pelton device disclosed here constitutes an improvement in Tesla turbine since it comprises the Tesla effect with the Pelton wheel effect. The Tesla-Pelton device can works as a turbine, as a pumping or as a compressor, in the same way that Tesla device. However, independently of the way or working, the Tesla-Pelton device presents higher efficiency than in original Tesla device since it has higher torque. This is obtained by the presence of some elliptical veins (11) in the surface of smooth Tesla discs causing a similar effect that happens in the Pelton wheel.
To the effect of this invention, it would be considered as vein any three-dimensional projection in the disc surface, which is made of the same disc material or other material, has constant height and thickness and has an elliptical shape.
An example of vein (11) that can be used is shown in Figure 3 (11 and 14) and in Figure 4 (11 and 13). The vein height (13) and the vein thickness (14) are determined according to the project specification but each vein must have a constant height, a constant thickness and have elliptical shape. The vein height (13) defines the distance between two parallel discs. The elliptical form of the vein (11) conducts the fluid direct to the exhaustion opening (9) since it is placed in one of the focus of this ellipse. Each vein (11) conducts the fluid flow to one exhaustion opening (9). Different veins, with different thickness and ellipse geometry can be present in the same smooth disc surface however;
each vein must have a constant height (13), thickness (14) and present an elliptical geometry as shown in Figure 3.
In one embodiment, the veins (11) are present in one side of the disc.
In one embodiment, the veins (11) are present in both sides of the disc.
In one embodiment, all the veins (11) in a smooth disc surface are Amended Pages 8/10 fÃ'T7. 2OO

equals.
In one embodiment, the veins (11) in a smooth disc surface are different.
The number of veins in a disc surface is determined by a project specification.
In one embodiment, the disc comprises one vein.
In one embodiment, the disc comprises more than one vein.
The elliptical curve shape of a vein (11) conducts the working fluid mass to the exhaustion port (9) as showed by the arrows (8) in Figure 3. In Figure 3, it is shown by the arrows (8) the fluid flow in a Tesla-Pelton turbine where the fluid is admitted in the edge of the disc and is directed by the effect of the vein elliptical curvature (11) to the exhaustion port (9).
A person skilled in the art must note that in the walls of the vein, by which flows the fluid, occurs also the fluid adherence effect in such a way that there are simultaneously the phenomena (or principles of working) of the Tesla turbine and the Pelton wheel.
The smooth side of the Tesla-Pelton disc, if not used to cover the vein space of another Tesla-Pelton disc, also presents the adherence effect like the smooth discs used in the originally Tesla turbine.
The area of the exhaustion port is defined according to the fluid mass to be drained off. The shape of the exhaustion port can be rounded (9) as showed in the Figure 3, has an elongated form (9) as showed in Figure 2 or presents another kind of shape since that is sufficient to drain off all the incident fluid mass.
The position of the exhaustion port relative to the center of the disc can vary according to the project specification. In a general way, as far as the exhaustion port is from the center, less torque can be generated since fewer surfaces of the veins would be available to the fluid mass.

u u 1 . S W:a I 9ER U1 In a turbine device, once passed by the exhaustion port (4), the fluid mass is conducted by a pressure difference inside the turbine, to one of the two sides where it reaches the environment.
The opening showed in the centre of the disc (12) in Figure 3 is filled by the device shaft which is a solid bar. This kind of shaft, enables the use of higher pressure condition of the fluid than in some similar systems that have a non-solid bar as shaft.
The number of discs used in a parallel disc turbine as in Tesla turbine is variable according to the project specifications. It is possible, for example, use just Tesla-Pelton discs, smooth original Tesla discs intercalated with Tesla-Pelton discs or any other kind of disc combination intercalated with Tesla-Pelton discs. The combination of Tesla-Pelton discs with the smooth discs used in the original Tesla turbine allows to change the proportion between speed and torque, that means, more Tesla-Pelton discs increase torque and reduce speed and vice versa.

EXAMPLE: TESLA-PELTON TURBINE WHICH DISCS PRESENTS EIGHT VEINS
The Tesla-Pelton turbine disclosed here presents all the smooth discs with eight equal veins in one surface (Figures 3 and 4) and eight equal exhaustion ports (9). All the veins (11) have elliptical shape and have circular exhaustion ports.

The Tesla-Pelton device disclosed here constitutes an improvement in Tesla turbine since it comprises the Tesla effect with the Pelton wheel effect. The Tesla-Pelton device can works as a turbine, as a pumping or as a compressor, in the same way that Tesla device. However, independently of the way or working, the Tesla-Pelton device presents higher efficiency than in original Tesla device since it has higher torque. This is obtained by the presence of some elliptical veins (11) in the surface of smooth Tesla discs causing a similar effect that happens in the Pelton wheel.
To the effect of this invention, it would be considered as vein any three-dimensional projection in the disc surface, which is made of the same disc material or other material, has constant height and thickness and has an elliptical shape.
An example of vein (11) that can be used is shown in Figure 3 (11 and 14) and in Figure 4 (11 and 13). The vein height (13) and the vein thickness (14) are determined according to the project specification but each vein must have a constant height, a constant thickness and have elliptical shape. The vein height (13) defines the distance between two parallel discs. The elliptical form of the vein (11) conducts the fluid direct to the exhaustion opening (9) since it is placed in one of the focus of this ellipse. Each vein (11) conducts the fluid flow to one exhaustion opening (9). Different veins, with different thickness and ellipse geometry can be present in the same smooth disc surface however;
each vein must have a constant height (13), thickness (14) and present an elliptical geometry as shown in Figure 3.
In one embodiment, the veins (11) are present in one side of the disc.
In one embodiment, the veins (11) are present in both sides of the disc.
In one embodiment, all the veins (11) in a smooth disc surface are Amended Pages 8/10 fÃ'T7. 2OO

equals.
In one embodiment, the veins (11) in a smooth disc surface are different.
The number of veins in a disc surface is determined by a project specification.
In one embodiment, the disc comprises one vein.
In one embodiment, the disc comprises more than one vein.
The elliptical curve shape of a vein (11) conducts the working fluid mass to the exhaustion port (9) as showed by the arrows (8) in Figure 3. In Figure 3, it is shown by the arrows (8) the fluid flow in a Tesla-Pelton turbine where the fluid is admitted in the edge of the disc and is directed by the effect of the vein elliptical curvature (11) to the exhaustion port (9).
A person skilled in the art must note that in the walls of the vein, by which flows the fluid, occurs also the fluid adherence effect in such a way that there are simultaneously the phenomena (or principles of working) of the Tesla turbine and the Pelton wheel.
The smooth side of the Tesla-Pelton disc, if not used to cover the vein space of another Tesla-Pelton disc, also presents the adherence effect like the smooth discs used in the originally Tesla turbine.
The area of the exhaustion port is defined according to the fluid mass to be drained off. The shape of the exhaustion port can be rounded (9) as showed in the Figure 3, has an elongated form (9) as showed in Figure 2 or presents another kind of shape since that is sufficient to drain off all the incident fluid mass.
The position of the exhaustion port relative to the center of the disc can vary according to the project specification. In a general way, as far as the exhaustion port is from the center, less torque can be generated since fewer surfaces of the veins would be available to the fluid mass.
Amended Pages CA 02717698 2010-09-03 F .. F~
u u 1 . S W:a I 9ER U1 In a turbine device, once passed by the exhaustion port (4), the fluid mass is conducted by a pressure difference inside the turbine, to one of the two sides where it reaches the environment.
The opening showed in the centre of the disc (12) in Figure 3 is filled by the device shaft which is a solid bar. This kind of shaft, enables the use of higher pressure condition of the fluid than in some similar systems that have a non-solid bar as shaft.
The number of discs used in a parallel disc turbine as in Tesla turbine is variable according to the project specifications. It is possible, for example, use just Tesla-Pelton discs, smooth original Tesla discs intercalated with Tesla-Pelton discs or any other kind of disc combination intercalated with Tesla-Pelton discs. The combination of Tesla-Pelton discs with the smooth discs used in the original Tesla turbine allows to change the proportion between speed and torque, that means, more Tesla-Pelton discs increase torque and reduce speed and vice versa. This property allows the designer to adapt the turbine to the applications.
The kind and discs dimensions to be used in the device vary depending on the power that one wishes to obtain from the turbine. It means that increasing the number of discs and/or their dimensions increases the power supplied by the turbine. Working as a pump or as a compressor, the same device would be able to pump or compress greater fluid mass than the original Tesla.
