Coherent Vortex Simulation (CVS), A Semi-Deterministic Turbulence Model Using Wavelets

  title={Coherent Vortex Simulation (CVS), A Semi-Deterministic Turbulence Model Using Wavelets},
  author={Marie Farge and Kai Schneider},
  journal={Flow, Turbulence and Combustion},
In the spirit of Ha Minh's semi-deterministic model, we propose a new method for computing fully-developed turbulent flows, called Coherent Vortex Simulation (CVS). It is based on the observation that turbulent flows contain both an organized part, the coherent vortices, and a random part, the incoherent background flow. The separation into coherent and incoherent contributions is done using the wavelet coefficients of the vorticity field and the Biot–Savart kernel to reconstruct the coherent… Expand
