摘要
应用摄动理论导出了粘性／无粘性流动的匹配条件，与边界层方程联立形成能计及粘性／无粘性干扰效应的模型方程。同时引用等效吮吸理论对该模型方程与全位势方程进行交替迭代求解，建立了计算高雷诺数流动的一种快速收敛的粘性／无粘性分区算法。计算结果表明该算法适用于包括小尺度分离的流动；与传统的半逆解法相比。
A matching relation on viscous/inviscid interactive flows is deduced,based on the perturbation theory,and coupled with boundary layer equations to form an interactive mode for the equations.A domain decomposition technique can then be constructed,utilizing the transpiration theory,by imposing an iterative proceduce through alternatively solving the interactive mode and the full potential equation.The method has proved to be effective for computing high Reynolds numbers flows with subsonic and transonic free stream Mach numbers.The numerical results presented in this paper demonstrate significant improvement of computational efficiency in comparison with the traditional semi inverse procedure.
