Abstract

Abstract:

This study was implemented for satisfying the demand of aerodynamic physics applications. On incoming flow conditions of a highenthalpy arc wind tunnel, the polypropylene ablation effect on electron density in a vehicle wake was investigated both computationally and experimentally. Numerical results agree well with the relevant experimental ones, and the numerical precision of electron density is largely improved with no more than one magnitude error.
