Abstract
Boundary layers subject to an adverse pressure gradient are very often encountered in flows around bodies, and represent a severe test case for the numerical simulation methods. The prediction of the flow characteristics in the regions subject to an adverse pressure gradient, of the separation and of the subsequent flow development represent a real challenge for the modelling techniques used in the simulations.
Most of the studies that can be found in literature are for flows over a flat plate with an imposed pressure gradient and are usually either experiments or direct numerical simulations. An interesting test case is constituted by the flow around a 3D prolate spheroid. This flow has been investigated experimentally, for purpose of validation of CFD methodologies, in the NWG DLR and F1 ONERA wind tunnels, has been considered in the E.U. funded project ECARP and is part of the datebase of ERCOFTAC and FLOWNET.
This document will focus mainly on the studies performed during the ECARP project.
