|Abstract:||The stretched-vortex subgrid model is used in conjunction with a fourth-order finite-difference method and artificial damping to run large-eddy simulations of decaying turbulence. By tuning the strength of the damping and the overlap between the subgrid model cutoff length-scale and the computational grid spacing, it is possible to obtain results that are independent of the grid spacing and consistent with reference simulations using a high-resolution spectral method. Artificial damping is useful for controlling numerical dispersion in large-eddy simulations of turbulent mixing.|
