Numerical Simulation of Turbulent Flow Through Concentric Annuli with a One-Equation-Type SGS Model

Abstract

Large eddy simulation (LES) with a one-equation-type subgrid scale model proposed by Okamoto-Shima is performed for turbulent flow through concentric annuli. The low-level turbulence quantities and shear stress budget in the inner region are well reproduced by the present LES. However, due to coarse grid resolution, there are disagreements between the DNS and LES results in the outer region.
