Development of CFD-DEM coupled solver for arbitrarily-shaped particle-laden flows

Popis výsledku v původním jazyce

Computational fluid dynamics (CFD) has become a commonly used method to simulate industrial processes. However, it cannot simulate processes, such as sedimentation or fluidization, that involve freely moving larger solid particles. While new methods combining CFD and discrete element method (DEM) have been studied to overcome this constraint, they are mostly focused on spherical particles only. Here, we present a strongly coupled CFD-DEM solver capable of simulating the movement of arbitrarily-shaped particles dispersed in a fluid. The particles are assumed to be large enough to affect the fluid flow and distributed densely enough to interact with both the computational domain boundaries and with each other. The newly introduced solver is intended to simulate fully coupled particle-laden flows with individual particles spanning multiple domain discretization elements.
