Abstract

Two nonequilibrium hypersonic CFD tools are compared to one another, including tightly-coupled radiation. DPLR and LAURA have different models for the separation of nonequilibrium energy. As a result, results from both codes show significant differences in flowfield temperatures. The flows considered in the present paper are from FIRE II, and from Stardust reentry. Both codes predict convective heat fluxes on the vehicle surfaces within 5% of one another. However, there are significant differences in predicted radiative transport, as well as in the effects of flowfield coupling. The present comparison demonstrates that, for future calculations, free electron temperature needs to be coupled to the vibrational temperature. in DPLR.
