  • In order to evaluate the uncertainties in CFD computations of the stagnation point heat flux, a physical criterion was developed. Based on a quasi-one-dmiensional hypothesis along stagnation line, a new stagnation flow model was applied which contributes to obtain the governing equations of the flow near the stagnation point at hypersonic speeds. From the above equations, a set of compatibility relations was given at the stagnation point and along the stagnation line, which consist of the physical criterion for checking the accuracy in stagnation point heat flux computations. Eventually, verification of the criterion was made among various numerical results.
