Turbulent concentration field with Sc=50 was investigated via large eddy simulation. Dynamic mixed model for the passive scalar was tested in a strong shear layer. Both mean and rms eddy diffusivities were shown to be reduced in the middle of the channel as the Schmidt number becomes large. A sudden increase of SGS turbulent Prandtl number in the vicinity of the wall suggests that more careful choice of filter size is required to capture the subgrid-scale dynamics correctly in this region when analyzing high Schmidt number flow.
