A semi-implicit multi-fluid SPH algorithm suitable for GPU
Abstract
Multi-fluid flows are a common problem in process and naval engineering. In this paper an incompressible Smoothed Particle Hydrodynamics (SPH) algorithm is presented, to solve multi-fluid flows with high density ratios (≤ 1000). The results of the Rayleigh-Taylor instability and the rising bubble test case are compared with the results obtained by a weakly compressible SPH algorithm with respect to the results obtained by grid-based solvers.
