An improved moving particle semi-implicit method for interfacial flows
Xiao Wen,Weiwen Zhao,Decheng Wan +2 more
TL;DR: In this paper, the improved moving particle semi-implicit (IMPS) method is further developed into a multiphase method by introducing various multi-phase models and applied to a variety of 2D/3D simulations of interfacial flows, including Rayleigh-Taylor instability, bubble rising, dam-break flow and internal solitary waves.

Efficient algorithms for the realistic simulation of fluids
TL;DR: Two free-surface simulations in the GPU are created: one fully in 3D and another restricted only to the upper surface of a big bulk of fluid, limiting the simulation domain to 2D, with high parallelism provided by actual consumer-level GPUs.
