ANGELINO, M. ...et al., Large-eddy simulations of high Reynolds number jets with a suitable subgrid-scale model for solver dependency study. Presented at the 11th International ERCOFTAC Symposium on Engineering Turbulence Modelling and Measurements, Palermo, Italy, Sept. 21-23.
Large-eddy simulations are performed of a turbulent round jet at Ma=0.5 and 0.9. The solver dependency is explored on computationally affordable
grids of 5 and 20 million grid points, by taking advantage of the consistency of the subgrid-scale σ -model. Three different solvers are tested. With all three, the
computed mean and second-order fluctuating quantities of the turbulent near field compare favorably with measurements, for both Mach numbers and both grids,
showing the strength of the σ -model in adapting to different flow conditions and grid refinements.
