Test simulation of heat environment in high enthalpy nonequilibrium flow and effects

To examine the material's performance in arc-jet tunnel, the heat transfer in flight is simulated by duplicating the surface pressure and total enthalpy based on the partial simulation. The conditions of the partial simulation method are analyzed. And the flow fields of two scale spheres are viewed by numerically solving the axisymmetric nonequilibrium Navier-Stokes equations. Effects on heat transfer and heat protection material are analyzed. It is demonstrated that the test heat transfer is lower in nonequlibrium flow when using partial simulation method, especially for lower catalytic efficiency surface. And because the thermal enthalpy is lower, the test degree for high temperature material is insufficient.
