Abstract
Based on two-dimensional full Navier ‒ Stokes equations the flow about stagnation point of spherically blunted body at hypersonic flight in the atmosphere of the Earth is investigated. The problem is being solved taking into account non-equilibrium physical-chemical processes (vibration relaxation, vibration-dissociation coupling, dissociation, chemical reactions, ionization). Convective heat fluxes at the stagnation point are compared to ones obtained using simplified engineering technique.
