A Generalized Finite Difference Scheme for Multiphase Flow

This paper presents a GPU-based, incompressible, multiphase generalized finite difference solver for simulating flow. The method includes dampening scheme that allows large density ratio cases to be simulated. Two verification studies are performed by the relaxation of square droplet surrounded light fluid and bubble rising in denser fluid. is also used simulate collision binary droplets at moderate Reynolds numbers (250–550). effects surface tension explored this work considering with Weber 8 180 ratios 2:1 1000:1. robustness highlighted when resolving thin structures arising both high low We = 180.
