Abstract (en)
[origin: US4397613A] In order to reduce the intermixing of air and exhaust gases in the cells of gas dynamic compression wave machines caused by the formation of shear layer vortices, the geometry of the leading side of the high pressure inlet orifice facing the bucket wheel has a curved convex or convex-polygonal configuration. Also, the ends of cell walls at the gas inlet ends thereof can be of a profiled configuration to further improve the gas flow conditions in the cells.
Abstract (de)
Zur Verminderung der Vermischung von Luft und Abgasen in gasdynamischen Druckwellenmaschinen wird vorgeschlagen, daß zur Verhinderung von Scherschichtwirbeln die Geometrie der Hochdruckgas-Eintrittsöffnungen (12) an der Mündung zum Zellenrand eine konvexe oder konvexpolygonale Profilform (5) aufweist, und daß weiterhin zur Erzielung einer besseren Zellenströmung die gasseitigen Enden der Zellenwände ebenfalls profilartig (10) ausgebildet werden.
