Abstract:
In this paper, we generalize the solid boundary condition where a one-sided Riemann solver is introduced to determine the fluid–solid interaction for weakly compressible smoothed particle hydrodynamics (SPH) presented in Zhang et al. (2017) to model multi-phase flows with large density ratio and multi-phase fluid–structure interaction (FSI) in multi-resolution scenario. Compared with the boundary condition proposed by Adami et al. (2012) where solid is discretized by dummy particles whose physic...     »
