Several typical hypersonic vehicle flowfields are simulated by using the conservation form of Navier-Stokes equations with multi-species
nonequilibrium molecular thermal excitation and chemical reactions based on the high-resolution TVD scheme. The aerothermodynamic properties(such as convective heat flux)and the thermo-chemical nonequilibrium phenomenon of hypersonic-continuum flowfields are obtained during reentry trajectory
and these results are in good agreement with experiment and flight data. By analyzing and comparing the difference of the hypersonic vehicle reentry flowfields in multiple cases
the predictive results
such as wall heat flux
aerodynamic-force coefficients
particularly the thermal nonequilibrium areas in the computational domain
are achieved to benefit the design of vehicle thermal protection system.
