A semi-inverse viscous/inviscid coupling technique for the calculations of compressible airfoil flows is presented. The Euler equations in integral form are solved in the inviscid part and the integral compressible boundary-layer equations in inverse form are solved in the viscous part. Both displacement and curvature effects have been included in the wake computation. Interaction is realized using the equivalent sources method. This technique has been applied to the calculation of the aerodynamic characteristics of airfoils both in subsonic and transonic regimes. It has been shown that the contributions of body displacement, wake displacement, and wake curvature effects are particularly important in the evaluation of the aerodynamic coefficients, especially drag. Different ways of computing the equivalent sources fluxes in the wake and the influence of the fixed-wake dividing streamline shape have been investigated and are discussed. |
