Numerical Simulation of Chemical Non-Equilibrium Flow in Hydrocarbon Fuel Scramjet Nozzle

Abstract:

Based on 8-specice, 12-step finite-rate chemical reaction models, the chemical non-equilibrium flows of hydrocarbon fuel scramjet single expansion ramp nozzle (SERN) were numerical simulated. The chemical dynamic characteristics of flow in SERN were analyzed in detail. The performances of SERN were compared at various inlet static temperatures. The numerical results show that the chemical non-equilibrium effect had great influence on the performance of the nozzle at the relatively high inlet static temperature. However, influence induced by chemical non-equilibrium effect can be neglected when nozzle inlet static temperature is less than 2500K.
