Abstract

In this paper the turbulent, incompressible and unsteady viscous flow around a circular cylinder is numerically simulated and the imposed fluid forces are calculated. The RANDOM VORTEX METHOD (RVM) with the using of a Large-Eddy Simulation (LES), as a turbulence modelling, is developed to investigate the fluid flow around a circular cylinder. A LES of TURBULENT FLOW is applied to account for the effect of turbulence in the wake. The Navier-Stokes equations are filtered by LES and transformed to computational domain by a general conformal transformation. The fil- tered equations are solved by an operator splitting where the velocity is found from Cloud-in-Cell (CIC) method and the diffusion equation is modeled by random walks (RW). The numerical results lift, darg coefficients and Strouhal number are in reasonable agreement with experimental results.
