MODELING OF SEGREGATION IN A HORIZONTAL ROTATING CYLINDER USING DEM

Abstract

In this work we have investigated segregation of granular particles inside a horizontally rotating cylinder using open source software package LIGGGHTS.In first part of the thesis we have described radial segregation for spherical particles. We have measured degree of segregation and studied how the segregation pattern evolves with time. In the later half we investigated effect of particle shape on the degree of segregation. Specially taking all combination of prolate and oblate spheroids, their size segregation was analysed. It was found that segregation is more pronounced for oblate - oblate mixture as compared to prolate - prolate mixture
