Definitions

  • This invention relates to a wind-solar chimney developed to convert the kinetic energy of the air and the heat energy of the sun into mechanical energy.
  • Turbines used in energy production today are used to convert the kinetic energy found in fluids such as water, wind, steam and gas into mechanical energy and then into electrical energy. Many types of turbines have been developed for this purpose.
  • the first known methods used to benefit from the energy of fluids are based on the principle of converting the drag effect of fluids into mechanical energy by a wheel.
  • Known examples for this method are pelton turbines in hydraulics and Savonius turbines in wind.
  • the propeller speed cannot exceed the fluid speed.
  • the amount and continuity of the electrical energy produced depending on the mechanical energy obtained is limited by the fluid velocity.
  • This limitation of energy production also reduces the efficiency of the energy produced.
  • the most important technical problem of wind turbines with vertical shaft operating with drag force is that a part of the turbine cannot be used because the rotating propeller has to reverse the fluid direction in half of each revolution completed. This technical problem reduces the efficiency of turbines using the drag force of fluids.
  • buoyancy of fluids In the state of the technique, devices that have high electrical energy production capacity and are used in energy generation applications created by the combination of more than one turbine use the buoyancy of fluids. In this method, fluid passes on both sides of the wings and creates a lift force on the wings. Examples of this method in the state of the technique; Kaplan turbine in hydraulics, steam turbines in gas and conventional wind turbines in air. Two basic principles are valid for propellers and propeller blades that use the lifting force of fluids, the basic operating modes of which are described above:
  • Thermodynamic method in solar energy The sun's rays are concentrated in a narrow area with parabolic reflectors, and the energy of a fluid (oil, water, etc.) heated in this way is converted into mechanical energy by known methods (steam boiler, turbine, etc.). In the state of the technique, when heat is applied to the fluids, they expand, their pressure increases, and this situation reaches up to phase change, as in the example of water-steam.
  • Known devices used to benefit from heat energy are hot water and steam boilers.
  • Photovoltaic method in solar energy With this widely used and known method, the energy in light photons is converted into electrical energy. This method, known as solar panel in practice, is widely used.
  • the wings are sweeping the surface.
  • this sweeping surface which is perpendicular to the wind direction, efficiently, the blades must sweep at high speed.
  • the tip speed of the wing tips can increase 6-8 times the wind speed, it is only possible to obtain a certain amount of energy from the swept surface.
  • the instantaneous energy passing through the swept surface is expressed as !/2*A*V 3 .
  • A is the surface swept by the blades
  • V is the wind speed.
  • the turbines In order to dampen the wakes, the turbines are placed in a staggered manner, leaving significant distances between the turbines. This reduces the overall efficiency of the wind harvest.
  • the design is derived from windmills as of its origin. Conversions carried out in modem wind turbines, extending the blade with propeller characteristics as much as possible, developing it with aviation technique, providing material flexibility, etc. such as transformations.
  • Conventional wind turbines are very sensitive to horizontal and vertical wind angles.
  • the lattice rotor turbine which is the subject of the patent application numbered TR 2013/11899, with vertical axis (to the direction of air flow) and cylindrical sweeping in the invention, produces high rotational motion with the components of the lift force and drag forces of the air passing on both sides of the airfoil section blade.
  • This turbine uses the wind power in half a turn and rotates against the wind in the other half turn.
  • a wind shield is used to prevent this. Carrying and enlarging this shield by the turbine construction arises as a technical problem. Increasing the wing length is also a problem for large designs. Since the resultant lift and drag forces change depending on the position of the wing, it is necessary to use powerful flywheels to ensure torque uniformity. This system cannot be used in sunlight in any way
  • Savonius turbines are machines that use the pressure difference created by the drag force of the wind on the turbine blades with S-shaped cross-section.
  • the turbine shaft is vertical and operates independently of the wind direction.
  • the rotor of this turbine makes half of its rotation against the wind and loses power significantly under the drag force of the wind.
  • the drag force of the air is used, the more efficient lifting force cannot be used.
  • These turbines can only operate in a vertical position and the system cannot utilize sunlight in any way.
  • Darrieus turbines are machines that produce rotational movement under the wind with the effect of air buoyancy by connecting the blades with symmetrical airfoil-shaped cross-sections to a vertical axis.
  • the weakness caused by the symmetrical blade shape in the first design has been tried to be eliminated in later designs and many other turbines have been developed on the basic design of this turbine until today. In practice, it is used as a wind and water turbine on a certain scale.
  • the fact that the blade section used in this turbine is symmetrical or very limitedly asymmetrical significantly affects the performance of the turbine to benefit from the aerodynamic lift force. Mainly, it takes advantage of the lift force generated by the head wind generated by the air passing over the airfoil section during rotation.
  • the wind is directed to two vertical shaft turbines from both sides of a fixed guide vane.
  • the fixed guide vane also shields the turbine half sections and the air is directed to the unswept sections only. Thus, it is aimed not to lose power while turning against the wind.
  • the blade design was inspired by the Darrieus wind turbine.
  • a rotation mechanism has been considered on the carrier body to always face the wind at the best angle. In this way, it differs from turbines such as Darrieus and Savonius, which operate independently of the wind direction.
  • the ends of the wings of this tribune are not fixed. There is also no other support on the wings along the entire wing.
  • the invention described in the document numbered US8403622B2 relates to a turbine with blades arranged around the rotor, whose fluid operates as axial inlet and radial outlet (such as a radial fan or pump) as opposed to the radial inlet and axial outlet flow in radial flow turbines.
  • the fluid passes from the center of the turbine towards the periphery.
  • the fluid naturally tends towards the side with less resistance.
  • the freely flowing fluid will tend outward from the open forehead of the device instead of entering the turbine. Since the fluid outlet is radial, in an open system flow, the fluid must be turned to the incoming direction, that is, to the axial direction.
  • the invention disclosed in document number W02013/005099 relates to nested wind turbines.
  • the air passing through the outermost turbine turns the smaller diameter turbine inside in the opposite direction compared to the outer one. It is aimed to add turbine powers to each other. Since the entire front receives the wind, the asymmetry of the blades must be very limited as in the Darrieus turbine.
  • the tightness of the nested rotors weakens the inflow of air, resulting in almost zero rotational effect on the rotor blades inside.
  • the invention described in the document US 2009/0159126A1 is an invention for obtaining concentrated sunlight by reflecting sunlight more than once and obtaining electrical energy with solar cells.
  • the light reflection scheme requires parabolic elements. These elements are special and costly elements due to their manufacture.
  • the solar cell at the end of the system must be special and costly considering the incoming concentrated sunlight. The system cannot benefit from the wind in any way.
  • This method which is widely used and commercialized, is the method in which high-tech products are used, and its main disadvantages are;
  • the product is modular and must be spread over a certain area

It has an advanced structural integrity with its venturi-diffuser air passage arrangement, turbine -alternator group, solar energy support battery, aerodynamic cap, wind direction blades, lower turning arrangement, sun beam collection arrangement and hot fluid circulation group. Thanks to its ability to continuously collect the sun's rays efficiently, it can also use the energy of the hot fluid as its efficiency.
  • the wind solar chimney In the development of the wind solar chimney,
