Recent Developments and New Results on The Flow Around an Inclined 6:1 Prolate Spheroid

Abstract

In the light of new computational resources and improved simulation tools we present new simulations of the flow around an inclined 6:1 prolate spheroid. We present the development of the flow from the symmetric and laminar case at Reynolds number 800 to the fully turbulent and highly asymmetric case at Reynolds number 3000. Already at Reynolds number 1000 we find strong transient behaviour in the flow that has not previously been reported. We attribute this finding to the improved grid resolution in this case. At Reynolds number 3000 the new computational setup we use in the present study shows a very long initial development phase with a symmetric wake configuration previously never reported before.
