Definitions
- the invention relates to a high-performance pressure wave source for generation individual high-energy pressure waves that can be repeated at short intervals each by igniting a defined volume of a combustible Fluid mixture, according to the preamble of claim 1.
- Relatively low power pressure and shock wave sources (around 10 to 100 mJ) are known in particular from medical technology, e.g. in the form of lithotripters.
- Current versions usually work according to the electromagnetic Principle, whereby plane, focusable by means of a coil / membrane unit Pressure waves are generated.
- a shock wave generator with a cross section expanded combustion chamber for generating detonation waves known from FR-A-1 378 962.
- DE-OS 39 21 808 describes a device for focused shock wave treatment known from tumors, with different ways of generating shock waves, e.g. using an explosive gas mixture (see claim 10). However, there are no indications for the constructive realization of this Given principles.
- Ignition also makes pressure waves flammable in reciprocating engines Fluid mixtures are generated, the ignition process being arbitrary in short time intervals is often repeatable.
- the fluid mixture at least the air fraction, is highly compressed (factor> 10), the combustion is caused by electrical spark ignition or injecting the fuel. It is generally a "soft", not too fast combustion aimed for, as detonation-like Burning processes the engine components (pistons, connecting rods, bearings, etc.) mechanically would overload.
- a transfer of this compression principle to others Pressure wave sources would be structurally and energetically relatively complex, i.e. little economical.
- the object of the invention On the basis of the principle of Acceleration of combustion up to detonation is the object of the invention in being a high power pressure wave source with short pulse duration and good repetition rate, which is relatively simple, handy, robust and is inexpensive and which works safely, reliably and economically.
- the pressure wave source comprises a combustion chamber in the form of a channel defined length with a cross-sectionally enlarged end.
- the face The end of the wide channel end forms an acoustic transmission element Acting membrane, with a discharge device in the area is available for the exhaust gas.
- the narrow end of the channel is used for feeding the mixture components and the ignition.
- vortex generators are provided, which the burning process accelerate to detonation.
- the geometric / volumetric Ratios is achieved that the majority of the mixture in the Area of the membrane is located, there burns off like an explosion and thus the Pressure wave generation causes.
- any acoustically conductive medium e.g. solid, liquid, gel-like, rubber-like
- Subclaims 2 to 9 contain preferred configurations of the high-performance pressure wave source according to the main claim.
- the high-performance pressure wave source 1 - hereinafter simply referred to as pressure wave source 1 - consists largely of a tube 2 with a round cross-section which varies over the length and which forms both a load-bearing housing and a flow channel / combustion chamber 3.
- the flow is from left to right, ie from the narrow to the trumpet-like widened tube end.
- the narrow tube end is provided with a feed device 4 for the components of a combustible fluid mixture, here air and hydrogen (H 2 ), the feed being able to take place continuously or intermittently during operation.
- the illustrated coaxial inflow of the components in the longitudinal direction of the pipe appears advantageous, but it is only one of many conceivable inflow variants.
- the fluid mixture consists of at least one fuel and one oxidizer, and the combustion behavior can be influenced via the mixing ratio, ie the deviation from the stoichiometric ratio. With a view to complete combustion, the attitude should tend to the "lean" side. Mixtures with more than two components are also conceivable, for example in order to influence the combustion behavior, the exhaust gas composition or the thermal load.
- the ignition device 5 works intermittently, with a high repetition rate (1 Hz or more) is aimed for. The most appropriate appears here electric spark ignition. Fast glow ignition may also be sufficient the requirements.
- the required acceleration of the erosion is achieved by means of several vortex generators 6 to 9, ie an increasingly turbulent flow character. This means that the burn-up speed can be increased to values well above 1000 m / s with short, high pressure peaks (detonation).
- the vortex generators 6 to 9 are designed, for example, as perforated screens with “tooth gaps” up to the tube wall. This can best be seen in the vortex generator 9, the central opening 10 of which is locally expanded in the form of a plurality of recesses 11 up to the tube wall. The smallest and the largest diameter of the vortex generator 9 are additionally indicated by dash-dotted lines.
- the cross-sectional and thus the volume distribution within the combustion chamber 3 is selected so that a large proportion of the fluid mixture detonates burns, i.e. behind the "flame acceleration zone" located.
- the trumpet-like shape shown with continuous cross-sectional expansion may be advantageous e.g. regarding the pressure wave propagation.
- other wall contours are also conceivable, e.g. with kinks and step-like diameter jumps. It can be enough be, two cylindrical pieces of pipe with very different diameters to connect via a perforated screen-like wall (jump in diameter). Tapered or multi-step transitions can also be used.
- combustion chamber cross sections do not have to be round either. square, rectangular or other geometries with and without corners are conceivable.
- the "pressure wave trumpet” shown could be achieved by using square instead of round cross sections while maintaining the steady, exponential Cross-sectional expansion to a "pressure wave horn” modified become.
- a large part of the volume of the combustion chamber burns off like a detonation, and that this volume part in Area of the membrane delimiting the combustion chamber at the end.
- the ignition process and the flame acceleration process should be restrict to a volumetrically small part of the combustion chamber. It is the case that the combustion chamber is full before each ignition process Length filled with flammable fluid mixture, i.e. is rinsed.
- a discharge device 12 is provided, here in the form of several, via the Scope of distributed outflow slots 13.
- the outflow process should be as possible cause no lateral reaction forces on the pressure wave source 1.
- the outflow slots 13 can also flaps, valves or other outflow organs be used.
- the combustion chamber 3 membrane 14 that closes at the end has both separating as well as a transferring function. On the one hand, it protects adjacent ones Substances before the immediate effects of the combustion process (Heat, combustion products etc.), on the other hand it forms a lossy, acoustic transmission element for the generated shock waves.
- the substance to be processed is either in physical contact with the membrane 14 Contact, or at least one other transmission medium, e.g. Gel, water or rubber, inserted between membrane and substance. The the latter, indirect contact is particularly given when the pressure waves generated are focused after the membrane.
- a focusing device 15 in is shown in dash-dot lines Form of an acoustic lens indicated. Clarity was on the details for the sake of doing without.
- the focusing device 15 or further focusing devices can only be detached with the Pressure wave source 1 connected, which corresponding connection options having.
