Abstract

Results are presented for numerical simulations of passive scalar mixing in homogeneous and sheared turbulent flows. These results are generated with the Linear Eddy Model (LEM). The discussion is based on the subgrid-scale statistics and it is shown that the LEM model reproduces correctly the structure of the scalar field in the case of high Reynolds numbers when all the relevant length scales are represented. Thanks to the results obtained, a simpler closure model for the subgrid scalar fluctuations is presented.
