A single-relaxation-time fluctuating lattice-Boltzmann (LB) model for direct numerical simulation (DNS) of particle Brownian motion is established by adding a fluctuating component to the lattice-Boltzmann equations (LBEs). The fluctuating term is proved to be the random stress tensor in fluctuating

On the basis of the potential flow theory, Lagrange's equation of motion is used to study the unsteady ground-effect problem. The forces and moments acting on the moving body are solved in terms of the derivatives of added masses in which the generalized Taylor's formulae are applied. The singular i
## Abstract Of all the models of turbulent motion that are based on a randomβwalk technique, the simplest are ones which simulate individual particle trajectories. The accuracies of two such models are assessed by applying them to lowβlevel diffusion in the atmosphere. It is found that one based on
