Application of a viscousinviscid interaction procedure to predict separated flows with heat transfer
Abstract
A viscousinviscid interaction procedure is described for predicting heat transfer in separated flows. The separating flow in a rearwardfacing step/asymmetric channel expansion is considered. For viscous regions, the boundarylayer momentum and continuity equations are solved inversely in a coupled manner by a finitedifference numerical scheme. The streamwise convective term is altered to permit marching the solution through regions of reversed flow. The inviscid flow is computed by numerically solving the Laplace equation for streamfunction in the region bounded by the displacement surfaces used in the inverse boundarylayer solution. The viscous and inviscid solutions are repeated iteratively until the edge velocities obtained from both solutions are in agreement. Predictions using this method compare favorably with experimental data and other predictions.
