Solution of particulate viscous flow over a two dimensional cylinder

The effect of solid particles on the fluid flow over a two-dimensional cylinder is analyzed, introducing into the analysis particles which rebound from the cylinder surface. The Lagrangian formulation is adopted for the particles, and the Eulerian formulation for the continuous phase. The equations are numerically solved for a cylinder Reynolds number of 40 and a cylinder diameter of 3.175 mm. The stream function and vorticity transport form of the equations of motion of the fluid, including the interphase force terms, are solved using a factored ADI scheme developed by Davis et al. (1972, 1979). The difference in particle paths between the potential flow and the viscous flow solutions for 100 micron diameter particles is shown.
