Abstract
Heat transfer in granular system is very important for science studies and industrial designs. Here we developed the code of heat transfer in granular system (including three heat conduction modes and heat radiation between particles) and integrate this code with our previous DEM code on Graphics Processing Units (GPUs). A simple experiment was made and a comparison between numerical results and experiment of heat transfer in granular packs shows a good validity of our code. The scalability test was performed and it shows that the time cost of calculation of heat transfer is acceptable. Therefore, a large-scale simulation of granular system with considering both of dynamic behavior and heat transfer is feasible. This work could be very helpful for design of granular-flow target systems.
