Interface Tracking and Applications — Lesson 3

This lesson covers the concept of two-phase flow and heat transfer, focusing on interface tracking methodologies. It delves into the volume of fluid methodology, explaining how to understand reconstruction schemes of interface from the data of volume of fluid in different cells. The lesson also provides a case study using volume of fluid-based freeware, demonstrating how to install the freeware, set model parameters, run a case, and evaluate the results. It further discusses the finite volume approach, the discretization of the domain, and the conservation of mass, momentum, and energy. The lesson concludes with a detailed explanation of the JERIS flow solver, a freeware for two-phase flow simulations.
