LES of flow over a circular cylinder at high Reynolds number

Abstract

Turbulent flow past a circular cylinder at Re = 1.4 × 105 has been analysed using Large Eddy Simulation (LES) approach solving filtered unsteady 3D NS equations coupled to Smagorinsky and dynamic subgrid scale (SGS) models. These simulations have been carried out using a parallel multiblock structured code which employs an implicit second-order accurate pressure-based finite volume method for solving Navier-Stokes equations for unsteady turbulent incompressible flow situations. The predictions are validated against detailed measurement data for mean as well as turbulence quantities. © IUTAM Symposium on Bluff Body Flows, Blubof 2011.
