A parametric study of ethylene-fueled scramjet combustion

Abstract

Ignition-delay distances for ethylene fuel injected into a supersonic combustor are modeled for jet-in-crossflow and shear-layer fuel-injection schemes using analytical models for entrainment and mixing, coupled with detailed chemical-kinetics simulations. Ignition delay distances are calculated for a two-dimensional parameter space of assumed vehicle flight Mach number and fuel-preheat stagnation temperature. The sensitivity of the ignition delays to these parameters is compared and discussed for the two fuel-injection schemes.
