Numerical Analysis of RCS Jet in Hypersonic Flights 912063

A transversely injected jet into a hypersonic flow is simulated numerically in order to study the flow field of the injection jet in the hypersonic atmosphere, its heat flux on the body surface and the moments working on the body. The flowfields is governed by the two-dimentional Reynolds averaged full Navier-Stokes equations with an algebraic eddy viscosity model developed by Baldwin-Lomax. The governing equations are solved using the Harten-Yee type TVD and central difference schemes to the convex and viscous terms, respectively. The real gas effect is considered in the numerical analysis. The jets injected across the main flows of Mach 10 and 15 are compared.
