Real Gas Effect on a Standard Model Electre

摘要：

　　A parallel three-dimensional code with Dunn and Kangs 7 species and 7 reaction model is developed to study the real gas effect on a standard model,referred as to Electre,from which flight data exits.It is shown that the heat flux results are consistent with flight data.Then the detailed flow features of a hypersonic flow around the forebody of the sphere-cone vehicle under different attack angle,altitude and Mach number under catalytic and non-catalytic boundaries are studied.As is shown,the real gas effects are mainly prominent in some regions of quite thin shock wave layers closing to the wall surface,and make the outstanding distance of shock wave short.The heat flux under full catalytic wall boundary condition is higher than that under non-catalytic condition,the bigger the attack angle,the more obvious this variance and the less electron number density on the wall.The higher the flight altitude,the lower oxygen dissociation and nitrogen and the heat flux on the stagnation point.
