Pseudo-particle modeling (PPM) is a particle method (PM) proposed in 1996. Though it is effective for the simulation of local phenomena in particle-fluid systems, its application to practical systems is still limited by computational cost. Therefore, macro-scale PPM, or MaPPM is proposed, which combines finite difference (FD) with weighted averaging techniques to upgrade particle interactions to the...
A comparative study on mesh-based and mesh-less Computational Fluid Dynamics (CFD) approaches coupled with the Discrete Element Method (DEM) is presented. As the mesh-based CFD approach a Finite Volume Method (FVM) is used. A Smoothed Particle Hydrodynamics (SPH) method represents mesh-less CFD. The unresolved fluid model is governed by the locally averaged Navier-Stokes equations. A newly developed...
