Simulations of solid particle in a lid-driven cavity flow using Lattice Boltzmann method

The purpose of this study is to investigate the behaviour of a solid particle suspended in a two-dimensional viscous flow. The flow considered takes place in a closed square cavity, driven along its upper face by a translating lid. Second order upwind Lattice Boltzmann method computations are perfor...
