Two-Phase Flow Modeling in with COMSOL - Complete Tutorial | Learn with BK

In this video, I walk you through a complete tutorial on simulating two-phase flow using COMSOL Multiphysics. You'll learn how to set up a two-phase flow model, define the geometry, assign materials, apply physics interfaces, and track the fluid interface using the Level Set method. This simulation covers the interaction between air and water, demonstrating how to handle fluid dynamics, pressure, velocity fields, and interface tracking.

Great video! I really appreciate the clear explanation. Can you please guide how to model water vapors emerging from the top into water, and how to calculate the heat and mass transfer rates. Any guidance or advice on how to approach this would be amazing! Thanks again for the valuable content! ❤

Thank you for this tutorial. Could you enhance this remarkable work by adding the phase change behavior when heating liquid water

Can you please make a demo video of Laser melting simulation in Comsol, how Solid material melts and the flow like a fluid after melting using two phase flow in level set or Phase field method
