Asymptotics of steady axisymmetric flow of incompressible fluid past a bluff body at high Reynolds number

Abstract

Steady axisymmetric separated flow at high Reynolds number is considered. It is shown that the body scale flow does not correspond to the Kirchhoff model because near the body there is a fairly strong reversed flow causing the secondary separation which is observed in numerical computations. Quantitative theoretical results are compared with the numerical results.
