The algorithm presented in this work allows for numerical generation of the geometry of a random packed beds of cylinders, Raschig rings and Intalox saddles. During the simulation, based on a simplified mechanics of the filling process, the particles are dropped sequentially into a cylindrical container. Various packing densities are obtained depending on the magnitude CF of the artificial radial force. It has been shown that the results are sensitive to CF only when its value is much smaller than gravity and realistic porosity is obtained for CF comparable or larger than gravity.
