Surface recombination effects on surface friction of reentry vehicles

摘要：

　　For the research needs on thermal environment of reentry vehicles,a simulation method is involved to study the surface recombination effect on surface friction by solving the 3-D Navier-Stokes equations.A CEV liked outline is involved to achieve the simulation.The results show that the surface friction differs from various catalytic conditions,and the difference is obviously around the high compressed area,but small in the major area and backward area.Surface recombination makes big molecule congregate to the wall,which causes larger velocity gradient.
