Discrete Element Simulation of Cascading Mode of Granular Particles and their Heat Transfer in a Rotating Cylinder
Abstract: A discrete element method (DEM) study is conducted to investigate the mixing and heat-transfer characteristics of spherical particles under slipping mode and flow regimes of a rotating tumbler. In this paper, heat transfer in rotating drums operated in a Cascading mode is assessed. The focus is on direct heating operations at low to medium temperatures, where thermal radiation is unimportant. It is shown that heat transfer from the covered wall to the particle bed is the dominant mechanism in supplying heat to the bed. . If heat is supplied to the boundaries of the particle bed rapidly, and macroscopic particle mixing is rapid, then heat transfer within the bed may be controlled by either or both of particle wall heat transfer and heat conduction within individual particles depending upon the physical properties of particles. Although theoretical analyses are principally used in this work. This paper addresses heat conduction in granular systems under Cascading mode in a rotating cylinder. The influence of material properties on the contact heat transfer coefficient between the covered wall surface and the solid bed was investigated.
