主　　题：Oscillating grid quasi-isotropic homogenous turbulence mean flow lattice Boltzmann method 

摘      要：The lattice Boltzmann method is used to simulate the oscillating-grid turbulence directly with the aim to reproduce the experimental results obtained in laboratory. The numerical results compare relatively well with the experimental data through dete- rmining the spatial variation of the turbulence characteristics at a distance from the grid. it is shown that the turbulence produced is homogenous quasi-isotropic in case of the negligible mean flow and the absence of secondary circulations near the grid. The direct numerical simulation of the oscillating-grid turbulence based on the lattice Boltzmann method is validated and serves as the founda- tion for the direct simulation of particle-turbulence interactions.
