Abstract

Thermal transfer of particulate beds is an important property for many industrial processes as well as for the storage of particulate material. This study is aimed at modeling the granular flow and heat generated between particles in contact. The multi-contact system modeling is performed by the Discrete Elements Method (DEM). The modeling of thermal effects arising from friction process is carried out by taking into account heat transfer resulting from mechanical energy dissipation during friction. The thermal transfers are linked to the contact conductance using Hertz's theory and the influence of the forces map. As an example, we simulated the heat generation during the discharge of a silo. Influence of the friction coefficient on the granular flow and heat transfer has been investigated through some numerical examples. This modeling enables to understand better the phenomena at the contact point between particles as well as the heat transfer for a great number of particles in motion from their intrinsic mechanical properties and contact conductance. This modelling enables to understand better the phenomena at the contact point between particles as well as the heat energy behaviour of a great number of particles in motion from their thermomechanical properties and contact conductance.
