Fuel-vortex interactions for enhanced mixing in supersonic flow.

摘要

n experimental investigation was conducted to compare the supersonic mixing performance between a novel aerodynamic ramp injector and a physical ramp injector. The aerodynamic ramp injector consisted of nine, flush-wall jets arranged to produce multiplicative fuel-vortex interactions for mixing enhancement in a supersonic main flow. The physical ramp injector was a previously optimized and tested swept-ramp design. Test conditions included a Mach 2.0 freestream of air with a Reynolds number of
