Unsteady flow around a circular cylinder at postcritical Reynolds numbers is simulated by the vortex method with a boundary-layer turbulence model. In the fractional step scheme, the vortex-in-cell method with a polar mesh is used for the convection of point vortices and random walks are superimpose

We present an adaptive wavelet method to integrate the velocityvorticity formulation of the two-dimensional Navier-Stokes equations coupled with a penalisation technique to handle efficiently solid boundaries of arbitrary shape. We demonstrate the validity of this method, called coherent vortex simu
## Abstract In this paper the vortex shedding around a heated/cooled circular cylinder is numerically simulated by solving the timeβdependent NavierβStokes and energy equations. A finite element method that is referred to as the threeβstep TaylorβGalerkin method is used to compute these equations.
