Low Speed Separation.

Abstract

Two approaches are considered for the high Reynolds number separated flow computational problem: these are high-order finite difference methods and Fourier Transform methods. A technique called 'reduction to periodicity; which allows the use of the FFT on non-periodic problems is tested and verified. This technique is shown to be a worthwile contribution to computational fluid dynamics, and does address one aspect of the high Reynolds number problem, but it does not by itself allow the accurate solution of high Reynolds number separated flows.
