A Numerical Method for High Reynolds Number Viscous Separated Flow.

Abstract

The Navier-Stokes equation is solved by a single-pass marching process, which overcomes the mathematical difficulties imposed, by transforming the solution in the direction normal to the flow into a spectral plane. The method has been verified, as far as possible. However, a precise determination of accuracy is clouded by the uncertainties introduced by turbulence and the modeling thereof. Nevertheless, it has been shown that the method yields reasonable results both in a full solution to the flow around a shaped body, and in a variety of plate flows with and without pressure gradients.
