Detached eddy simulation of homogeneous isotropic turbulence

  • Detached eddy simulation was used to simulate decaying homogeneous isotropic turbulence. Simulation results were compared to the experimental data of Comte-Bellot and Corrsin, showing that the detached eddy simulation of homogeneous isotropic turbulence was acceptable. The method proposed by Rogallo was used to construct the initial velocity field and the generated turbulence field fit the Von Karman spectrum. In the choosing of convective flux scheme, second-order centered scheme and fourth-order skew-symmetric scheme and upwind low-diffusion flux-splitting scheme were used respectively to check the numerical dissipation and suitability in the detached eddy simulation of homogeneous isotropic turbulence. Meanwhile, the cutoff wave number was changed with the varying of computational region and turbulence model parameters. In this way, the simulation results shows how energy spectra and energy accumulation for small scales are influenced by the variety of the cutoff wave number.
