A fully three-dimensional viscous-inviscid interaction method is developed for the calculation of steady incompressible flow over transport wing configurations. The external inviscid flow is computed with a constant-potential (Dirichlet) panel method and the viscous layer is described with three turbulent integral boundary layer equations, in a Cartesian coordinate system. The interaction between the two regions is modelled via the wall transpiration velocity concept. From the used external flow formulation approximations for the edge velocity components are derived, required for the quasi-simultaneous coupling. The boundary layer equations are discretised with a finite volume scheme, and solved simultaneously with the approximations for the external flow by Newton’s method. Results are presented for unswept and swept wing cases and are compared with experiment and other computational results
