Abstract

The KATS-US solver uses a modified Volume Averaged Navier-Stokes set of equations to model the interaction between ablative material and hypersonic flow. The approach uses a single set of equations for both fluid and porous domains. In the present work, a two-temperature model is added to the code. The implementation of the model was verified by comparing to published results. The thermal non-equilibrium effect within the porous medium is presented and discussed. A new equation is proposed that can be used to model vibrational accommodation inside the porous medium.
