Development of CFD Solver for Four-Way Coupled Particle-Laden Flows

Abstract:
Computational fluid dynamics (CFD) simulations containing freely moving bodies are still a challenging topic. More so, if the bodies are large enough to affect the fluid flow and distributed densely enough to come in contact both with the boundaries of the computational domain and with each other. In this work, we concentrate on the topic of simulation of (i) irregular bodies with flow-induced movement and contact with computational domain boundaries taken into account, and (ii) bodies entrained by the fluid and coming in contact not only with the domain boundaries but also with each other. The developed modeling approach is based on the hybrid fictitious domain-immersed boundary method extended by the discrete element method. The present contribution is focused on presentation of simulation principles and results of initial benchmark cases.
