Abstract : Consideration of three-dimensional inverse boundary-layer codes to threat separated flow is motivated by the success enjoyed by two-dimensional inverse boundary-layer codes. Indeed, as was first shown by Catherall and Mangler, the separation singularity which occurs in the direct mode (integrating the boundary-layer equations with a prescribed inviscid outer edge velocity uinv) can be eliminated by using an inverse mode. With an inverse mode some other quantity such as displacement thickness is prescribed, and the outer edge velocity which we call uvis is generated by the boundary-layer calculation. A coupling scheme must then be devised to insure that velocity uinv from the outer inviscid flow agrees with uvis from the boundary layer.
