A 3D Channel Flow Simulation at RE(sub tau) = 180 Using a Rational LES Model

Abstract

This paper presents numerical results obtained by applying an LES model based on a rational (subdiagonal Pade') approximation in tHe wave number space. We used a spectral element code to test this LES model and tbe Smagorinsky model with Van Driest damping in the numerical simulation of a 3D channel flow at Re(sub T) = 180. The corresponding results were compared with the fine DNS simulation of Moser, Kim, and Mansour.
