Abstract: A self-adaptive upwinding method for large eddy simulation (LES) has been describe in cross-flow in jets. The method is an extension of an existing Reynolds-averaged Navier-Stokes (RANS) code to an LES code by adjusting the contribution of the upwinding term to the convective flux. This adjustment is essentially controlled by reducing the upwind contribution in Roe MUSCL scheme. For the comparison of flow profiles obtained from the self-adaptive upwind LES code the experimental measurements of Andreopoulos and Rodi [1] are considered. The jet-to-cross-flow velocity ratio considered is 0.5 at a Reynolds number of 20,500 based on the jet bulk velocity and the jet diameter. In general, a reasonable agreement with the measurements is obtained. However, an intense backflow near the flat wall is observed. Further a vortex formation is observed behind at a distance of 0.6D from the jet axis. Copyright © 2010 by ASME.
