Triple-Deck Structure Solution to the Problem of Separating Flows

Abstract

Within the range of the triple-deck structure theory, we used the inner layer equation to find a solution to the problem of separating flow over backfacing steps and compressional corners. We obtained results identical with those of Navier Stokes numerical solution and experimental wind tunnel values. In this paper we use the upwind scheme with third order accuracy and Gauss Seidel iteration with the relaxation factor; this permits an increase in the accuracy of the numerical calculations and in the convergence rate.
