Numerical Experiments on Deconvolution Applied to LES in the Modeling of Turbulent Flow
Published in 2013
The Large Eddy Simulation is an important method to simulate turbulent flow. It does not produce a closed system of equations, to achieve this it is necessary to model the not-closed terms. The deconvolution can be used for this purpose. In this study some numerical experiments on this topic are performed with COMSOL Multiphysics®. The main objectives are to find an efficient way to implement deconvolution and to evaluate its numerical behavior, with particular attention to the boundary conditions, or rather to their LES-deconvolution modeling.
