Definitions

  • the present invention relates to a gas dynamic pressure wave machine, essentially consisting of a cellular wheel, which rotates in a central part and between a respective air-side and gas-side part provided with inlet and outlet openings, the geometry of the high-pressure gas inlet opening at the mouth of the cell wheel being shaped like a profile .
  • the exhaust gas relaxes and then escapes into the low-pressure gas outlet, while in the air-filled room.
  • Part of the fresh air drawn in is compressed and is pushed out into the high pressure duct.
  • the remaining fresh air portion is flushed through the cellular wheel into the low-pressure gas outlet and thus causes the exhaust gases to exit completely.
  • a pressure wave machine of the aforementioned type is known from US Patent 3 1074 1622, wherein the openings of the outlet channels on the air-side side part shaped profile rounded and the inlet mouths am.gas stoolen side member having a groove-shaped, ie konkavpolygonales profile.
  • This is intended to achieve a gradually increasing compression wave which, when striking the air-profiled mouth, should result in a reduced reflection wave, in particular in the event of extreme incorrect tuning in the lower speed range of the pressure wave machine.
  • this design is intended to achieve a reduced outflow at the high-pressure inlet opening and a reduced inflow from the high-pressure inlet. This is intended to correct the deviations of the wave transit times from the ideal transit time.
  • the present problem of weakening the mixing process in the cells cannot be solved by these measures.
  • the above object is thereby ge resolves that the profile shape is convex or convex-polygonal to prevent shear-layer eddies.
  • the width of the wall part inclined towards the cell edge corresponds to approximately 75% of the distance between two cell walls.
  • the radius of curvature of the mouth advantageously corresponds to approximately half the distance between two cell walls.
  • the newly proposed design of the mouth of the high-pressure gas inlet opening creates a vortex that is the same at the design speed as that at the cell front edge, but has an opposite direction of rotation. At this speed, air and exhaust gas are not mixed. It is particularly advantageous that such profiles are easy to manufacture.
  • the gas-side ends of the cell walls can be designed in a profile-like manner in order to achieve a better cell flow in cooperation with the profiled mouth.
  • Fig. 1, 1 shows a part of a cellular wheel with individual cells 2, which rotates between an exhaust-side side part 3 and a pleasure-side side part 4 in the direction of arrow 11.
  • the high-pressure gas inlet opening 12 and a low-pressure gas outlet opening 13 are provided on the exhaust-side side part 3, while a high-pressure air outlet opening 14 and a low-pressure air inlet opening 15 are arranged on the air-side side part 4.
  • the opening 5 to the cellular wheel 1 is convex, the radius r of the convex curvature corresponding to approximately half the distance b between two cell walls 16.
  • the exhaust gas shown in dots enters the cell at the moment a cell 2 is opened in the direction provided by the profiled mouth 5.
  • an outflow bubble which formed would move in the counterflow direction of the rounded mouth 5, as indicated by the arrow 6, and close cause a complete separation of the flow.
  • the aim is that the two opposite vertebrae, that is, the vertebra 6 at the mouth 5 and the vertebrae (arrow 7) at the front edge of the cell 2, have the same strength and therefore one as possible generate sharp and perpendicular to the cell walls 16 vertical partition 8 between air and exhaust gas shown in dashed lines.
  • the exhaust-side ends 10 of the cell walls 16 are designed in profile-like manner, whereby an almost complete suppression of the opening edge vortex can be achieved by the action of the profile-related front edge vortex. All other opening and closing edges 5 'at the outlet and inlet openings have no profiles.
  • FIG. 2 the same parts are provided with the same reference symbols as in FIG. 1.
  • the mouth 5 is formed from two wall parts 17, 18 which meet at an obtuse angle, for example of 160 °, in such a way that both wall parts 17, 18 have the same angle with respect to the horizontal.
  • the wall parts 17, 18 preferably formed so that the width a of the cell Rad 1 inclined wall part 18 corresponds to approximately 75% of the distance b between two cell walls 16.
