Large eddy simulation of flow past a circular cylinder at Reynolds number 3900

Abstract

The flow past circular cylinders at a subcritical Reynolds number of 3900 has been studied extensively, both experimentally and numerically. This makes it an ideal test case for validation of numerical techniques. Results from large eddy simulations with two different subgrid scale models are presented and compared to the experimental results of Ong and Wallace [11], Lourenco and Shih [7] and Norberg [10]; and the numerical data of Kravchenko and Moin [6] and Beaudan and Moin [1]. The results are obtained by solving the incompressible Navier- Stokes equations using a finite volume method. The subgrid scale models-one equation eddy viscosity and Smagorinsky- show good agreement with the afore..
