| 内容記述 | A numerical method for solving the transonic viscous-inviscid flow interaction is newly developed. The finite difference equations derived from the basic equations for viscous and inviscid flows and the coupling condition between them constitute a system of nonlinear simultaneous equations having a tridiagonal coefficient matrix at each longitudinal station, which can be easily solved using SLOR method. The process is just like that of inviscid flow calculations except that the unknown column vector at each station includes three boundary layer variables. Solutions for the inviscid flow and the boundary layer are obtained simultaneously without any difficulty. The method is applied to the flow over a divergent wall and a circular-arc airfoil respectively, where separation and/or wake flow pattern may appear. Calculations are executed for several cases of Reynolds numbers and Mach numbers. In order to demonstrate the applicability of the present approach, the results are compared with the experimental and another numerical ones and the effects of the various parameters on the interaction phenomenon are examined. | |||||||
