Large-eddy simulation for urban micro-meteorology

Session B4


Validation of large-eddy simulation (LES) computations of flows over an array of cubes with imposed periodic inflow-outflow condition is described. Then, a method of generation of appropriate inflow data for such flows is proposed and the results are compared with those using periodic boundary conditions in the streamwise direction and wind tunnel measurements [3]. Finally, some results obtained using the inflow method for an oscillatory through-flow combined with a steady current are discussed.
