TL;DR: In this article, a volume-of-fluid (VOF) model that is refined with smoothing operations was used to minimise spurious or non-physical velocities at the micro-scale, in order to obtain more accurate velocity results from the microchannel simulations.

TL;DR: An algorithm is proposed and developed whereby the interfacial area is ascertained within the framework of the volume-of-fluid (VOF) multiphase model whereby a plane cutting an orthogonal mesh cell is considered and the area can be approximated as the area of the resulting polygon from the plane cut.

TL;DR: In this paper, an improved VOF model based on smoothing functions that can effectively minimise the issue of spurious velocities, which causes numerical simulations in microchannels to be less accurate.

TL;DR: In this article, a coupled multiphase-multicomponent model was developed for micro-scale simulations of mass transfer in the volume-of-fluid (VOF) model, where smoothing operations were applied in the surface tension force calculation to minimize spurious velocities.

TL;DR: In this article, a numerical investigation is conducted to study the formation and dissolution process of CO2 bubbles within silicone oil in a cross-junction microchannel, where a coupled multiphase-multicomponent computational fluid dynamics model based on the volume-of-fluid method is used, which is able to capture the physics of multi-phase bubble formation, dissolution mass transfer, and the tracking of the dissolved CO2 species.
