Experiments and simulation of torque values in anton paar powder cell by using different impeller shapes and particle size

Experiments and DEM simulations for the torque measured in a bed of glass beads with an Anton Paar powder cell rheometer were carried out for two different particle sizes (2 and 4 mm) and four different blade shape and geometry. Each impeller shape was used to interfere different mechanical coefficient properties between the particles and the best agreement between experimental and simulation results were chosen. As a way to calibrate the DEM software for glass beads
