Abstract

A series of typical points of a hypersonic flight trajectory with Ma from 8 to 22 and altitudes from 47.8km to 72.8km for a R=0.4m sphere are simulated by solving conservative Navier-Stokes equations including thermo-chemical nonequilibium effects. Results illustrate that different thermodynamic and chemical kinetic models almost have no impacts on the prediction of the aerodynamic heating in the hypersonic nonequilibrium flow. It is also found that there is only 10% difference on the heat transfer calculation between two thermal conductivity models: Eucken relation and Gupta fitting formula.
