Three-dimensional separated flow structure over prolate spheroids

Abstract

Colour poster paints were used for water-tunnel visualization of the surface flow patterns over prolate spheroids of axis-ratios b/a = ½, ⅓ and ¼ at incidence from 0-90°. Results display the surface flow pattern over the entire body presumably for the first time in terms of completeness and clarify unsettled questions in the literature.
