Inviscid hypersonic flow simulations using an explicit scheme
Abstract
Within the flamework of the collaboration between IMHEF-EPFL and CERFACS, a 2D Euler solver which incorporates the effects of equilibrium and nonequilibrium air chemistry has been developed. The Euler equations are solved using a space-centered explicit time marching scheme augmented by artificial dissipation terms. The incorporation of equilibrium air chemistry was straightforward and did not require modifications to the numerical scheme. Nonequilibrium chemistry has been implemented without using special procedures to treat the chemical source term. Calculations showed that the solver can be used successfully in predicting dissociating high-speed air flows.
