ABSTRACT: We review grain-resolving Navier-Stokes simulations for a variety of multiphase flow processes. These simulations are based on an Immersed Boundary approach, which accurately captures the flow around each particle and in each pore space. We will discuss several different applications, among them particle sedimentation, particle-turbulence interaction and submerged granular collapse processes. One focus will be on the influence of cohesive forces in such flows, especially the formation and break-up of aggregates consisting of several individual particles.
