In this paper, a simple but effective modeling of the turbulence response to a sudden adverse pressure gradient has been incorporated into a boundary layer auxiliary equation. The modification attempts to reproduce the lag process of the response, so that the predicted accuracy of boundary layer parameters (displacement thickness, momentum thickness, shape factor and skin friction coefficient) in shock-wave boundary layer interaction and airfoil trailing edge regions at transonic speed is improved. The modification also improves the preceding parameters accuracy at high subsonic speeds, in particular, in airfoil trailing-edge region. This computational method is simple and convenient, and only a little computational time is needed. If about 120 interpolation points are used alone the surface of the airfoil, the computation time is about 25, minutes on a Felix c-125 computer.
