We present a new turbulence model to compute fully developed turbulent flows. The method is based on the solution of the wavelet filtered Navier‐Stokes equations in vorticity‐velocity formulation using an adaptive wavelet discretization. As application we present a Coherent Vortex Simulation (CVS) of a two‐dimensional mixing layer and compare the results with those obtained with Direct Numerical Simulation (DNS).
