A viscous-inviscid interaction procedure for computing two-dimensional incompressible separated channel flows
Abstract
A viscous-inviscid interaction scheme is presented for computing steady, two-dimensional, incompressible laminar and turbulent flows in two-dimensional duct expansions. The viscous flow solutions are obtained by solving the boundary-layer equations inversely in a coupled manner by a finite-difference scheme; the inviscid flow is computed by numerically solving the Laplace equation for streamfunction using an ADI finite-difference procedure. The viscous and inviscid solutions are matched iteratively along displacement surfaces. The solutions obtained for separated flows in channel expansions using the present scheme compare favorably with experimental data.
