Momentum conserving methods that reduce particle clustering in SPH

By SP Stan Korzilius, ACH Kruisbrink, WHA Wil Schilders, MJH Martijn Anthonissen and T Yue


In this paper we present two remedies for particle clustering in SPH. Since particle clustering is the consequence of a diminishing kernel gradient for small inter-particle distances, the first method uses a convex kernel with a non-zero kernel gradient at the origin. The second method is based on inter-particle collisions. They are both compared with conventional SPH in several case studies. The results show a great improvement in particle distribution, where particle clustering is strongly reduced or absent, with only a small influence on the accuracy of the computations
