DLR τ-Code for High Enthalpy Flows

The development of an equilibrium chemistry model for the DLR τ-Code has extended its ability to simulate high enthalpy flows, such as those around reentry vehicles or within high speed test facilities. Details of the development of the chemistry model, and some test cases, are included in this paper. Also presented is an improved axisymmetry treatment for the code, aimed at producing accurate and noise-free solutions for common hypersonic applications such as blunt bodies and shock tunnels.
