Axisymmetric impingement of a hot jet on a flat plate: Equilibrium flow analysis of high-temperature air (Q1894407)

A TVD scheme is used to solve the conservative form of the Euler equations with source terms describing the underexpanded inviscid supersonic jet with high temperature, impinging against a flat plate. High temperature effects associated with molecular vibrations are taken into account by means of the specific heat ratio and the speed of sound which are given by explicit polynomial functions of thermodynamic variables. The results indicate that the temperature effect is very strong in the recompression regions behind schock waves for high reservoir temperature jets.
