A simple and economical iterative scheme is presented for calculating turbulent shear layers with significant pressure gradients normal to the plane of the layer, such as occur on highly-curved surfaces or near the trailing edges of lifting airfoils, and for matching the shear-layer calculations to calculations of the inviscid external flow. The iteration required to solve the elliptic equations describing the shear layer is combined with the iteration needed for the matching, and the finite-difference solution of the normal-component momentum equation is a simple quadrature at each iteration. Therefore computing time is little greater than in conventional displacement-surface calculations that ignore normal pressure gradients. (Jensen)
