Abstract

The study presented herein is concerned with the development of a computational algorithm for viscous-inviscid interactions with application to two-dimensional transonic airfoil flows. The inner viscous flow is treated by means of the integral method of Whitfield, while the external flow is calculated by Jameson's Euler equation code. The two flows are matched by a linearized boundary condition at the airfoil surface.

Of particular interest is the use of a time-dependent boundary layer calculation method since it has been determined that a time-dependent method is desirable for extending the interaction method to three-dimensional flows.

In general, it is found that the agreement between the theoretical prediction and experimental data is satisfactory for engineering calculations.
