The Use of Lattice Boltzmann Method for Particulate Flow Analysis

Abstract:

In this article, we present a lattice Boltzmann method to treat moving solid particles in a fluid. 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 a floor of straight channel were simulated at two difference aspect ratio and wide range of Reynolds numbers. Two different shapes of cavity were selected to investigate their effect of the efficiency of solid particle removal. Current study found that the rate of particle removal is significantly dependence on the Reynolds number of the flow and the shape of the cavity. Excellent agreement with the results computed by other methods indicates the capability of the scheme in predicting particulate problem.
