This paper presents the first results of a study aimed at delineating the processes leading to ignition of liquid fuel jets injected transverse to a hot supersonic air stream. The tests were conducted at Mach 1.8 with a nominal stagnation pressure of 100 psia and stagnation temperatures from 500-1800 F. Kerosone, CS2 and water were used as the injectants. The observations were in the form of direct, top-view photos, temperature measurements and topview, infrared Thermographic 'photos to produce isotherm patterns. Attention was directed, in particular, at the surface layer formed on the wall near the injection port. (Buehn)
