P. Fischer and T. Iliescu, "A 3D Channel Flow Simulation at RE[sub \tau] = 180 Using a Rational LES Model," Preprint ANL/MCS-P893-0801, August 2001. [pdf]

This paper presents numerical results obtained by applying an LES model based on a rational (subdiagonal Padé) approximation in the wave number space. We used a spectral element code to test this LES model, a coarse DNS, and the Smagorinsky model with Van Driest damping in the numerical simulation of a 3D channel flow at Re[sub \tau] = 180. The corresponding results were compared with the fine DNS simulation of Moser, Kim, and Mansour.
