Modeling Two-Phase Flows Using SPH Method

A multi-phase SPH method for macroscopic and mesoscopic flows

A multi-phase smoothed particle hydrodynamics (SPH) method for both macroscopic and mesoscopic flows is proposed. Since the particle-averaged spatial derivative approximations are derived from a particle smoothing function in which the neighboring particles only contribute to the specific volume, while maintaining mass conservation, the new method handles density discontinuities across phase in...

Modeling Two-Phase Flows on Moving Domains

Mudflows are catastrophic events that cause immense damage to infrastructure and life every year. Local authorities have been trying to mitigate the risk by zoning regulations as well as by building protection structures for many years. These measures have, however, in most cases been designed based on knowledge from past events. Numerical models have started emerging about 30 years ago. While ...

A Parallelizable Method for Two - Phase Flows

Numerical simulation of wave impact on a rigid wall using a two-phase compressible SPH method

In this paper, an SPH method based on the SPH–ALE formulation is used for modelling two-phase flows with large density ratios and realistic sound speeds. The SPH scheme is further improved to circumvent the tensile instability that may occur in the SPH simulations. The two-phase SPH solver is then used to model a benchmark problem of liquid impact on a rigid wall. The results are compared with ...
