Effects of Triangle Internals on Temperature Distribution of Granular Material in Rotating Horizontal Drum

Abstract

The DEM-based heat transfer model is carried out to investigate effects of triangle internals on temperature distribution of granular material in rotating horizontal drum. The model is verified by comparing with literature published previously. The effect of triangle internals on temperature distribution of granular material accounting for triangle number and rotation speed is discussed. The results show that triangle internals breaking the vortex core zone involving low-velocity and mixing dead zone in the granular bed can effectively enhance heat transfer and temperature uniformity inside the drum. Heat transfer and temperature uniformity increased with increasing triangle number and rotating speed, but slightly increased as the value is higher.
