ANALYSIS OF DIFFERENT KINETIC MODELS OF HIGH TEMPERATURE AIR FOR INTERPRETATION OF THE FIRE-II EXPERIMENTAL DATA

摘要

Several kinetic models of gas phase reactions have been studied with CFD code NERAT for interpretation of aerothermodynamics of space vehicles entering into the Earth atmosphere at hyperbolic velocities. Conditions of the FIRE-II flight experiment were considered. It is shown that studied kinetic models (the Park model, the Dunn and Kang model, and the Martin model) provide acceptable agreement between convective heat fluxes on space vehicle surface, but the models give different temperature fields that can be significant for prediction of radiative heating.
