Momentum/continuity coupling with large non-isotropic momentum source terms
TL;DR: In this paper, a colocated variable pressure correction algorithm for control volumes of polyhedral/polygonal cell topologies is presented independent of spatial approximation, and the presence of non-isotropic momentum source terms is included in the proposed algorithm to ensure its applicability to multi-physics applications such as gas and particulate flows.
