Development of DEM-CFD Simulation of Combustion Flow in Incinerator with the Representative Particle Model

A simulation code based on the discrete element method (DEM) and computational fluid dynamics (CFD) coupling model was developed to simulate the behavior of radioactive cesium in waste incinerators. The waste lump was represented by particles in the simulation. The energy equation for a mixed gas, d...
