Abstract:
In the framework of the parabolic viscous shock layer theory (PVSL) the hypersonic
thermochemical nonequilibrium air flow over blunt body with catalytic surface moving along
prescribed aerodynamic reentry trajectory at incidence and slipping angles is investigated. The
interaction between vibrational relaxation and chemical proceses on the basis of a preferential
vibration-dissociation-exchange reactions coupling model (CVDEV) is taken into account.
The high accuracy implicit numerical algorithm is used, which does not imply symmetric
planes existence in flow and does not need a preliminary solution to the Stefan-Maxwell
relations with respect to the diffusion fluxes. The influence of the body shape, of the attack and slipping angles, of the heterogeneous chemical reactions model, of the freestream
parameters and of the vibrational nonequilibrium on the heat flux and of the equilibrium
surface temperature is analyzed.
