Description/Abstract

The numerical prediction of three-dimensional turbulent separation regions and the resulting unsteady vortical flow patterns within these regions is still poor. This paper presents detailed experimental data for steady onset flow around a truncated cylinder of height/diameter ratio of 1.0, mounted on a ground plane. The performance of Large Eddy Simulation (LES) and Unsteady Reynolds-Averaged Navier Stokes (URANS) methods are compared for this case. It is seen that on an identical grid, the LES simulations predict the separation region more accurately than the URANS model and at 75% of the computational cost.
