Fundamental Investigation of Numerical Simulation Method for Wet Powder Flow

Abstract

The calculation methods of Discrete Element Method (DEM) for wet powder flow are diverse, and lacking a unified assessment. In this study, four calculation methods, combining two approaches for bridge formation distance and liquid bridge force during particle contact, were applied to a rotating drum mixer. Comparisons of the results revealed the significant impact of calculation methods for wet powder on the outcomes. Moreover, comparison with experimental data revealed that the Liquid Film Contact model (LFC) demonstrated the ability to accurately represent experimental results even under high liquid content.
