Modelling of the Energy Dissipation Generated by Friction in Granular Flow Using the Discrete Element Method

摘要

This study is aimed at modeling the heat transfers in a multi-contact system. A model based on the detection of contacts and the evolution of heat transfers in particle flow has been developed drawing upon the Discrete Element Method (DEM). Through this work, we also model the heat flows generated by friction and collision. This modeling enables to understand better the phenomena at the contact point between particles as well as the heat energy behavior of a great number of particles in motion from their thermomechanical properties.
