摘要: Heat transfer in particulate beds has an important impact for many industrial processes as well the storage of material. This study is aimed at modeling granular flow and heat between particles during discharge a silo. A numerical model based on detection contacts evolution transfers particle been developed by using discrete element method (DEM). Through this study, we flows generated friction its conductance. Influence coefficient discharging velocity investigated through some examples. enables to understand better phenomena contact point great number motion from their intrinsic mechanical properties
