Abstract

Trajectories of a buoyant spherical solid particle in a linear shear flow were investigated at low Reynolds numbers. A two-dimensional CFD analysis was performed to simulate the solid-fluid flows. Our numerical model, the discrete phase element method, was used to model and simulate the fluid domain and particle motion as the solid phase. The reliability of the computational results was evaluated for the particle trajectory. The agreement between the numerical results with the experimental data was quantified.
