Abstract
Computational prediction of fluid-solid particle interaction in an expansion horizontal channel with wide range of Reynolds numbers. Lagrangian-Lagrangian numerical technique to predict the movement of solid particle. The method is based on mesocale scheme of lattice Boltzmann method for prediction of fluid dynamics and second Newton’s law for the dynamics of solid particles. The flow behaviour at the downstream of the expansion channel is critically dependence on the Reynolds number of the flow. The removal percentage of the contaminant critically dependence on the flow structure donwstream of the expansion channel. The strength of recirculation region plays significant role due to the step in the cavity.
