摘　　要：讨论壁面有引射的滑移边界条件的提法．利用ＣｈａｐｍａｎＥｎｓｋｏｇ速度分布函数，通过分析Ｋｎｕｄｓｅｎ层外缘和壁面处的质量、动量和能量等通量守恒，得到了有壁面引射的多组元气体有催化反应的壁面滑移边界条件方程组．利用粘性激波层方程和所得的边界条件对钝头体绕流驻点区的流场进行了计算。In this paper, the slip boundary conditions with wall injection are discussed. From analysis of mass, momentum and energy flux balance equations at inner and outer edges of the Knudsen layer using the Chapman Enskog velocity distribution function, the system of slip boundary equations with wall injection and catalysis in a multicomponent gas mixture is derived in a general form. Numerical calculations are made for a hypersonic flow passing the stagnation region of a blunt body by using the Viscous Shock Layer (VSL) equations with the boundary conditions derived in the paper. The influence of the wall injection on the flow field and boundary conditions is investigated.
