CFD Investigation of Parameters Affecting Oil-Water Stratified Flow in a Channel [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2020
Stratified flow is a common occurrence for various internal flow based industrial multiphase flow patterns. This involves fully or partially well-defined interface which continuously evolve with space and time.

Computing curvature for volume of fluid methods using machine learning [PDF]

Journal of Computational Physics, 2019
In spite of considerable progress, computing curvature in Volume of Fluid (VOF) methods continues to be a challenge. The goal is to develop a function or a subroutine that returns the curvature in computational cells containing an interface separating two immiscible fluids, given the volume fraction in the cell and the adjacent cells.
