Theory for the Two-Phase Thin-Film Flow, Phase Field Interfaces
The Two-Phase Thin-Film Flow, Phase Field interfaces can be used to model the flow of two different, immiscible fluids in thin, narrow channels, where the exact position of the interface between the two fluids is of interest. The fluid-fluid interface is tracked using an auxiliary function on a fixed mesh. These methods account for differences in the two fluids’ densities and viscosities and include the effects of surface tension.
