Abstract
The aim of this investigation is validation and verification of solid particle interaction in a low Reynolds number fluid flows We evaluate the accuracy and reliability of discrete phase element method (DPM) for one/two solid particle interaction in a highly viscous flow in both cylindrical and rectangular Couette flow. The computational results (solution) based on ANSYS/FLUENT 14.0 is validated by experimental data. Unsteady DPM CFD simulations are performed to match the experimental setups. Particle trajectories in cylindrical and rectangular domains are studied. In the experiment, spherical particles are suspended in gravity-stratified Newtonian fluid, thus limiting their motion to a single plane. Their predominantly two-dimensional motion is driven by moving belts (or a rotating cylinder) that produce shear in the fluid. Several parameters of solid particle motion at a low Reynolds number are validated and verified. The uncertainty analysis for both numerical and experimental data is performed.
