In this numerical scheme, we solve the fluid phase using a mesoscale method of lattice Boltzmann scheme. The particle motion is governed by Newton's law thus following the Lagrangian approach. The dynamics of solid particle in a lid-driven cavity was investigated at a wide range of Reynolds numbers. The results of this study suggest that the particle trajectories are critically dependent on the magnitude of Reynolds Numbers and the vortex behaviour in the cavity. Good comparisons with other previous studies demonstrate the?multidisciplinary applications of the present scheme .
