Steady solutions in Lattice-Boltzmann computatons of turbulent flows: a method based on selective frequency damping
Résumé
The present study deals with the issue of convergence in Lattice-Boltzmann computations of turbulent flows using the Reynolds-Averaged Navier-Stokes (RANS) approach. A method to improve the convergence is proposed. It is inspired from the work of [1], regarding selective frequency damping (SFD). Preliminary results of the method are shown. The studied case is the flow around a cylinder at Reynolds number Re = 140000.
