“…For the 25° angle, a drag coefficient of 0.299 and a lift coefficient of 0.345 was obtained from the wind tunnel experiment, while the CFD simulation resulted in the values of 0.295 and 0.387 for drag and lift coefficient respectively. The RSM model showed an over estimation of the pressure coefficient over the slant angle, when compared to the pressure measurement made by Lienhart and Becker (2003). Han (1992) [9] performed aerodynamic shape optimization on Ahmed body with three shape parameters: backlight angle (0º to 30º), boat tail angle (0º to 30º) and ramp angle (0º to 20º).…”

In this paper, the Vorticity Confinement method (VC) is presented for the calculation of flow field around a bluff body. The VC method was originally proposed by Fan et al. The aim of the method is to capture small-scale vortical structures efficiently. The presented study assesses the VC method (namely the first formulation, referred to as VC-1, which involves first derivatives of velocity), for external aerodynamics presented here on a well documented simplified car -Ahmed bluff body with different slant angles, namely 25° and 35°. These slant angles were chosen because the 35° slant angle supports the boundary layer separation and therefore stronger wake (also stronger oscillations of the wake), while at the 25° slant angle no separation takes part and the wake is much weaker and also more stable. The VC method was applied using different values for the diffusion parameter and confinement
