Abstract

Large eddy simulation (LES) has been applied to prediction of the three-dimensional turbulent boundary layer (3DTBL) over a rotating disk. The filtered incompressible Navier-Stokes equations are solved using the fractional step method; subgrid scale (SGS) stresses are parameterized using the dynamic eddy viscosity model of Germano et al. (1991). A series of computations have been performed for a momentum thickness Reynolds number 1660 to investigate the effect of computational domain size and spatial resolution on simulation results. With increasing spatial resolution, LES predictions of mean velocities and second-order statistics converge towards the experimental measurements of Littell & Eaton (1994).
