Original abstract

In the paper, Vorticity Confinement method (VC) is presented for the calculation of flow field around a bluff body. VC method was originally proposed by Steinhoff et al. for the computation of thin vortical regions in the high Reynolds number incompressible flows. Steinhoff claims that VC is capable of capturing most of the main features of high-Re turbulent flows without the massive mesh resolution needed for Reynolds-Averaged Navier-Stokes (RANS) solutions or Large Eddy Simulation (LES). The aim of the method is to capture small-scale vortical structures efficiently. The presented study assesses the VC method, for external aerodynamics presented here on a well documented simplified car – Ahmed bluff body with different slant angles, namely 25 and 35 deg.
