TALK=T;RUN( 1, 1) DISPLAY 3-dimensional, polar, steady, elliptic simulation This case calculates the accumulation of two groups of particles, of different diameters, along the bottom of a circular pipe through which liquid flows from low z to high z. The particle slip velocities are normal to the continuous phase flow direction. The larger particles settle to the bottom of the pipe, forcing the smaller ones to rise with the displaced fluid.
