CFD-DEM Modeling of Dense Particulate Flows: Challenges and Development Wu, Chunliang
Talk: Regular Abstract: Dense particulate systems can exhibit complex flow structures and diverse flow patterns similar to those observed in their fluid-fluid counterparts. The pattern/structure formation is attributed to two interactions: the particle-fluid (P-F) and the particle–particle (P–P) interactions. CFD-DEM has proven to be an effective numerical tool to capture complex flow behavior in dense particulate systems. In this talk, I will discuss the challenges and developments of modeling dense particulate flow under CFD-DEM framework from both numerical and physical perspectives. Ongoing work on development of a new drag law by considering the effect of local heterogeneous structures will be highlighted.
