Comparison of Surface Tension Models for the Volume of Fluid Method
Processes, 2019 With the increasing use of Computational Fluid Dynamics to investigate multiphase flow scenarios, modelling surface tension effects has been a topic of active research. A well known associated problem is the generation of spurious velocities (or currents)

A volume of fluid method for simulating fluid/fluid interfaces in contact with solid boundaries
, 2015 In this paper, we present a novel approach to model the fluid/solid interaction forces in a direct solver of the Navier-Stokes equations based on the volume of fluid interface tracking method.

Modeling of vertical microplastic transport by rising bubbles
Microplastics and Nanoplastics, 2023 Microplastic particle concentration at the sea surface is critical for quantifying microplastic transport across the water-air interface. Previous studies suggest that the concentration at the sea surface is enhanced compared to bulk concentration, yet ...
