Liquid fuel jet injection into a simulated subsonic dump combustor
Abstract
Basic experimental studies of the injection of liquid fuel into a two dimensional flowfield designed to represent a sudden-expansion 'dump' combustor were performed under cold-flow conditions. Test conditions were as follows: 0.6 entrance Mach number, 25 PSIA total pressure, and nominally 75 F stagnation temperature. Two step heights were investigated, 1.0 in. in 0.5 in., corresponding to area ratios of 1.33 and 1.17. The investigation included Pitot and static pressure distributions, spark and streak shadowgraphs, surface flow visualization, direct photographs and videotape recordings.
