ABSTRACT

In this article, the lattice Boltzmann method (LBM) to predict moving solid particles in a fluid flow is presented. The scheme uses a uniform Eulerian grid for the flow domain and a Lagrangian grid to trace the dynamics of solid particles. The solid particles in a cavity located on the floor of a straight channel were simulated at two difference aspect ratios and a wide range of laminar Reynolds numbers. Two different shapes of cavity were selected to investigate their effect on the efficiency of the solid particles removal. The current study discovered that the rate of the particle removal depends significantly on the Reynolds number of the flow and the shape of the cavity. A fair agreement with the results obtained from other methods emphasizes the capability of the current scheme in predicting particulate problems.
