A fully coupled computational fluid dynamics (CFD) and discrete element method (DEM) model was calibrated using a draw down test (DDT) under submerged conditions. Momentum smoothing and cell clustering were used to model particles that were larger than the cells. The DEM input parameter values were initially set equal to those calibrated for the dry conditions. https://www.remtavares.com/best-offer-Merrick-Backcountry-Grain-Free-Kitten-Pate-Canned-Wet-Cat-Food-5-5-oz-Cans-Case-of-24-p14288-limited-choice/
