| Abstract: | A new numerical model was successfully developed for analyzing packed bed structures containing non-spherical solids such as cokes and the high-temperature melt trickle flow characteristics of such beds. This enables the direct three-dimensional analysis of packed beds that are difficult to visualize in experimental tests. The sophisticated smoothed particle hydrodynamics (SPH) method can track the motion of liquids without discriminating between continuous and dispersed phases. Meanwhile, the advanced discrete element method (DEM) is employed as a highly-accurate method for solid-particle motion simulation. It is a method using a contact force model that is expanded to capture the motion of 3-dimensionaly freely shaped rigid bodies. We used the boundary for the packed bed configured with non-spherical solids to carry out a trickle flow simulation. Based on this model, we carried out the largescale simulations, and perform case studies and other studies of statistical processing, and investigate the effects of both physical properties and packed bed formed from various types of non-spherical cokes. |
