Abstract

Presents four examples which were researched in a large eddy simulation (LES) of turbulence for engineering applications. Explains that, in the former two cases, developments of the advanced LES are indicated in a Smagorinsky model and in the treatments of the wall and the external boundary, and, in the later cases, the LES on the boundary fitted grids are applied using the finite different method (FDM) and the finite element method (FEM), where new numerical treatments, a composite grid technique and a modified scheme, are adopted for efficient calculations. Evaluates the results, and discusses the possible application of the LES for engineering problems.
