An accurate numerical prediction of solid particle fluid flow in a lid-driven cavity

Abstract

Research on solid particle flows has been quite intensive in the past decade. The difficulties associated with accurate predictions of the interactions between the solid and surrounding fluid. Hence, in the present paper, we focus on the simulation of lid driven cavity flow containing a solid particle immersed in an incompressible fluid. In the present analysis, we adopt an Eulerian Lagrangian approach where the solid particle is treated as a point in the cavity. To achieve the accuracy, the numerical scheme for the fluid is properly chosen so that the resultant force on the solid particle can be accurately determined. Our aim is to seek further improvement on the fundamental knowledge of the trajectories of a solid particle in a lid-driven cavity. To broaden our understanding of the particle dynamics in the cavity, we also study the vortex structure in the cavity which directly influence the trajectories of solid particle.
