Abstract: Shallow recirculating flows in an open-channel expansion are computed using a 2-D LES (Two-Dimensional Large Eddy Simulation) method. The Smagorin-sky model of the sub-grid scale is adapted in conjunction with a model for the bed-generated turbulence. Calculations are conducted for recirculating flows of different depths. The results obtained for the mean velocities, the contaminant concentrations, and the Reynolds stresses are compared with available labora-tory data. The values of the Smagorinsky parameter varying from 0.17 to 0.2 are selected to optimize the model performance.
