A finite volume approach to large eddy simulation of compressible, homogeneous, isotropic, decaying turbulence
Abstract
Finite volume techniques are used to perform large-eddy simulation of compressible, homogeneous, isotropic, decaying turbulence in a rectangular box. An analysis of the energy spectra obtained from the simulations shows that agreement with the Kolmogorov law for the inertial range is found only when an appropriate spatial discretization method is used. This agreement is obtained both for a low (0.05) and a moderate (0.6) Mach number when Smagorinsky's subgrid model is employed.
