abstract = {<p style="text-align: justify;">In this paper, air chemical non-equilibrium effects on the shock-induced
combustion flow are numerically investigated for a reaction control system (RCS) with
gaseous ethylene fuel by solving multi-component Navier-Stokes (N-S) equations. An
integrated numerical method is developed that considers two different chemical reaction
mechanisms: the high temperature air chemical non-equilibrium reactions and
ethylene-oxygen combustion reactions. The method is independently validated by
two types of reacting flow: the hypersonic air chemical non-equilibrium flow over a
sphere and supersonic ethylene-oxygen combustion flow for a dual combustion chamber.
Furthermore, the mixed reacting flow over a blunt cone with a transverse multi-component
gaseous jet is analyzed in detail. Numerical results indicate that air chemical
non-equilibrium effects could lead to a reduction of the shock detachment distance,
a decrease of the temperature behind the shock wave and a reduction of the combustion
products.</p>},
