A quasi-simultaneous viscous-inviscid coupling method is developed for the calculation of three-dimensional steady incompressible flow over transport wing configurations. The external inviscid flow is computed with a constant-potential (Dirichlet) panel method, constructed from a constant source and doublet distribution over the wing surface and wake. From the used external flow formulation three approximations for the velocity components are derived, required for the fully three-dimensional quasi-simultaneous viscous-inviscid interaction scheme. The viscous layer is described with three integral boundary layer equations, in a Cartesian coordinate system, which are solved simultaneously with the approximations for the external flow by Newton’s method. Results are presented for two three-dimensional wing flow cases, including separation, and comparisons are made with two-dimensional viscous-inviscid interaction results.
