Abstract:

Photographic data were obtained for the transverse injection of water and isopropyl alcohol from a flat-plate into airstreams having Mach numbers of 1.62 and 2.72. Jetfreestream dynamic pressure ratio, jet Reynolds and Weber numbers, and freestream Reynolds number were varied. Improved empirical equations for jet penetration and width were developed and substantiated for two sets of test conditions by detailed flowfield mapping 50 jet diameters downstream using pitot-pressure, cone-static-pressure, and heated sampling probes. An improved theoretical analysis was obtained.
