DEM modeling of high shear wet granulation of a simple system
High shear wet granulation (HSWG) is one of the most poorly understood processes with known difficulties in optimization and scale up. The purpose of the current study is to develop a DEM model which can be applied under dynamic process conditions with high predictive capacity to improve process ins...
