Abstract

1,184,099. Wind tunnels. AVIATEST G.m.b.H. 10 Oct., 1967 [11 Oct., 1966], No. 46334/67. Addition to 1,047,586. Heading B7G. In a modification of the method of producing supersonic fluid flows as claimed in Specification 1,047,586 wherein particles of the flowing medium are electrically charged, a supply duct 27 is supplied with a high velocity flow of mineral oil saturated with oxygen-free-nitrogen which is discharged through an expansion nozzle 14 into a transparent tube 16 from whence it passes through a convergent-divergent section 17, 28, a test model 36 being mounted on a stalk 35 in the tube 16. The jet from nozzle 14 evacuates the annular space 40 to a predetermined pressure drop, indicated by a manometer 29, whereupon a switch 41 is closed to connect a D.C. current source 42 of about 50,000 volts and the expansion nozzle 14 to form an electric field in tube 16 with maximum density in the vicinity of the edge 43 of nozzle 14.
