(8a) Validation of CFD-DEM Simulation of a Continuous Tablet Coating Process
World Congress on Particle Technology
Monday, April 23, 2018 - 8:00am to 8:23am
In this work we present a model to simulate the coating process in the ConsiGmaTM 160 mm and 320 mm coater using CFD-DEM. The eXtended Particle System (XPS) is used for the DEM simulation and is coupled to AVL Fire® for the CFD1. The validity of the simulation results, as well as our method for modeling the non-sphericity of the tablets, are shown. The simulations are compared to experimental results, including the quantitative comparisons of the tablet flow and bed shape, as well as coating-related parameters, such as average coating mass on the tablets, standard deviation and coefficient of variation.
