Modeling the Fluid Interface Between Immicible Liquids

The objective of the paper is to investigate and to model the dynamics of the water-oil interface in a rotational laminar flow induced by a spinning disk in a close vessel. Direct visualizations of the interface's evolution are correlated with the torque measurements and the numerical simulations performed with the VoF method implemented in ANSYS Fluent code. The main aim of the study is to compute the strain rate on the interfaces and to determine the regions with maximum viscous dissipation.
