Abstract

Aerodynamic heating calculation is one of key technologies for hypersonic vehicles.In this thesis, inviscid numerical answer was obtained via computation fluid dynamic method.Substituting the answer into the equations of engineering method, heat flux was got.In stagnation zone, heat flux was calculated using Fay-Riddle formula, and in non-stagnation zone, it was based on the reference enthalpy method.Compared with the experimental and pure CFD answer, feasibility of calculating heat flux of vehicle surface by combining the inviscid numerical answer outside the boundary layer and engineering method inside the boundary layer was verified.
