Calibration of a DEM contact model for wet industrial granular materials
Sahar Pourandi, P. Christian van der Sande, Igor A. Ostanin +1
This study presents and calibrates a Discrete Element Method (DEM) contact model for wet granular materials in the pendular regime. The model extends a previously calibrated dry co…
