Thermo-Mechanical Modelling of Granular Materials With Non-spherical Particle Shape
Abstract
In this grant a new capability to model heat transfer through granular materials with non-spherical shape has been developed. This has involved creating a new body-fitted grid solver designed to simulate intra-particle heat conduction through super-quadric (SQ) particles, coupling this new solver to a traditional Discrete Element Method (DEM) solver (which simulates inter-particle collisions) and implementing these coupled solvers on a hybrid CPU/GPU architecture for maximum computational efficiency. A 14-fold speed-up was noted in using the hybrid CPU/GPU architecture versus running purely on the CPU. This suggests that the use of hybrid CPU/GPU architectures is promising for the simulation of intra-body heat transfer in granular materials with non-spherical shape. Future work will involve applying this capability to study heat conduction in more realistic granular materials which will have impact in a variety of applications ranging from multi-phase reactors, catalytic processes and explosives.
