- Applications of the wavelet based coherent vortex extraction method are presented for homogeneous isotropic turbulence for different Reynolds numbers. We also summarize the developed adaptive multiresolution method for evolutionary PDEs. Then we show first fully adaptive computations of 3d mixing layers using Coherent Vortex Simulation. Features like local scale dependent time stepping are also illustrated and examples for one dimensional problems are given. Test cases on complex geometries like the periodic hill flow (with Reynolds numbers up to 37000) and an annular burner with a swirl number of S = 0.6 have been calculated based on the developed wavelet decomposition models. The extensive results presented show the robustness and good accuracy of the adopted wavelet approach for the various flows simulated.
