DEM simulations on the heat conduction in a particle mixer

  Understanding the heat transfer among particles with uneven temperature distribution is a key to powder processing.In this work,the discrete element method (DEM) is used to optimize the interior structure of a particle mixer with multiple baffles to achieve better heat transfer between two particulate materials.The simulation results show that optimal values exist for the number of baffles and their widths,slope angles and spacing to enhance heat transfer.The results are helpful to the design of a variety of process such as the ultra-fast pyrolysis in coal topping.
