Laminar Separated Flow over Nonlifting Ellipses.

Abstract

A theory is presented for the laminar separated flow over nonlifting ellipses as a function of thickness/chord ratio (t/c) and free stream Reynolds number. The theory includes the separated flow over a circular cylinder as the special case when (t/c) = 1. The theory involves a coupling of inviscid and viscous flow through a search method. The inviscid analysis provides the pressure which is used in the boundary layer program to locate the boundary layer separation points. Convergence occurs when the boundary layer separation points are equal to the assumed inviscid separation points. (Modified author abstract)
