LES for street-scale environment and its prospects
LES for street-scale environment and its prospects
In this paper we raise several issues, e.g. resolution, Reynolds number dependency, mesh quality and inflow boundary conditions for Large-Eddy Simulation (LES) of street scale flows, scalar dispersion and heat transfer within urban areas. Some of the issues are addressed extensively and some LES results of test cases are presented. The other issues are discussed and commented for further study. Finally we attempt to foresee prospects for the use of LES for urban environments with a computational domain size up to a few kilometers and a resolution down to one meter.

Abstract
In this paper we raise several issues, e.g. resolution, Reynolds number dependency, mesh quality and inflow boundary conditions for Large-Eddy Simulation (LES) of street scale flows, scalar dispersion and heat transfer within urban areas. Some of the issues are addressed extensively and some LES results of test cases are presented. The other issues are discussed and commented for further study. Finally we attempt to foresee prospects for the use of LES for urban environments with a computational domain size up to a few kilometers and a resolution down to one meter.
