Numerical Simulation of Decaying
نویسنده
چکیده
The present note is concerned with the numerical simulation of two{dimensional homogeneous decaying turbulence. We employ a Galerkin{type discretization in an adaptive basis of orthogonal wavelets. Therewith the solution is represented by means of a reduced basis being adapted at each time step. It is one of the rst times that wavelet decomposition of a turbulent ow eld is not only used for a posteriori analysis but directly for the computation of the ow in a reduced basis. A classical Fourier method furnishes a suitable reference solution.

We compare the lattice Boltzmann method (LBM) and Pseudo-Spectral (PS) method for direct numerical simulation of decaying homogeneous isotropic turbulence. In this study we use the generalized lattice Boltzmann equation (GLBE) with multiple-relaxationtime (MRT) collision model, which overcomes all the apparent defects in the popular lattice BGK equation. We first compare the instantaneous flow ...
متن کاملComparison between theoretical predictions and direct numerical simulation results for a decaying turbulent suspension.
A recently developed theoretical model for a turbulently flowing suspension has been applied to a homogeneous, isotropic, and decaying turbulent suspension. The predictions are compared with results from direct numerical simulations. The agreement is reasonable. Special attention is paid to a physical explanation of the influence of the particles on the turbulence of the carrier fluid.

Capabilities for turbulence calculations of the Lagrangian averaged Navier–Stokes ~LANS-a! equations are investigated in decaying and statistically stationary three-dimensional homogeneous and isotropic turbulence. Results of the LANS-a computations are analyzed by comparison with direct numerical simulation ~DNS! data and large eddy simulations. Two different decaying turbulence cases at moder...
