Abstract: To investigate the behavior of the particle-laid turbulent flows,a numerical model is presented through the lattice Boltzmann(LB)method with the large eddy simulation. The simulated settling velocity of the spherical particle agrees with the theoretical value and the measured result by the particle imaging velocimetry(PIV). Furthermore,the flow field around particles and the flow velocity in the tail are illustrated. The computed results are basically in accordance with the measured values. It verifies that the LB method and the large eddy simulation can be applied to simulating the particle-laid turbulent flows.
