Description/Abstract

This paper presents some of our most important conclusions from the work undertaken thus. We have found (i) that, perhaps surprisingly at first sight, LES for flows over such complex surfaces is in fact less technically demanding than for smooth surfaces at similar Reynolds numbers (the flow dynamics are dominated by obstacle-scale motions rather than thin boundary layers), (ii) that a highly efficient filter technique can be used to provide appropriate turbulence inlet conditions, and (iii) that the overall approach can yield flow and concentration results in good agreement with experimental data.
