Large-eddy simulations of high Reynolds number jets with a suitable subgrid-scale model for solver dependency study

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 sigma-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 sigma-model in adapting to different flow conditions and grid refinements
