Abstract

The flow past a bluff body is frequently associated with periodic vortex shedding. In this paper, the turbulent flow past a square cylinder is simulated by larg-eddy simulation. The Smagorinsky model (1963) is adopted as the SGS model for the subgrid Reynolds stress term. In addition, an upwind-biased scheme is used for discretizing the convection term to stabilize the numerical calculation. The effect of the upwinding is found to be rather significant. The magnitude of the numerical viscosity term of the upwind scheme is controlled to minimize its effect.
