Abstract

When turbulent flows are modelled by means of Large Eddy Simulation (LES), the characteristic length scale of the turbulent fluctuation needs to be resolved by the grid. In complex geometries this length scale varies substantially over the computational domain. The present paper proposes an approach to adjust the grid size in an LES adaptively such that the resolution capacity of a grid with a given number of points is used at best. This is done with so-called r-refinement. The paper presents the work of three groups collaborating on this issue.
