Calculation of free mixing layer on the base of large-eddy simulation

Large-eddy simulation of turbulent flow in the free mixing layer is considered on the base of some sub-grid scale models (Smagorinsky model, RNG-model, dynamics model and one-parameter differential model). The accuracy and effectiveness of different sub-grid scale models are compared. The ways of formulation of boundary conditions on the inlet boundary and construction of computational grid are discussed. Computational results of averaged and fluctuating flow properties including moments of high order are compared with the experimental data and available computational data.
