Description
This course is a beginner-friendly, step-by-step introduction to multiphase CFD using OpenFOAM, designed to help learners build confidence by starting with simple and clearly explained 2D cases. All examples are intentionally kept computationally light and conceptually clear, making the course ideal for students and first-time OpenFOAM users.
You will begin by understanding the fundamentals of multiphase flow, phase change, and multi-species modeling, and how these concepts are implemented in OpenFOAM. The course introduces key solvers such as interFoam, interIsoFoam, compressibleInterFoam, twoPhaseEulerFoam, and multiphase EulerFoam, with a clear explanation of when and why each solver should be used.
All simulations are based on simple 2D test cases, including water column collapse, rising air bubbles in water, interface tracking comparisons (VOF vs isoAdvector), Euler-Euler bubble flow, and basic multi-phase mixing cases. These carefully chosen examples allow you to focus on understanding the physics and solver setup without being overwhelmed by complex geometries or heavy meshes.
Strong emphasis is placed on hands-on case setup. You will learn how to define multiple phases and species, configure thermophysical properties, set initial and boundary conditions, choose appropriate interfacial models (such as drag and phase interaction), and correctly use dictionaries like controlDict, fvSchemes, fvSolution, and setFields.
The course also covers common beginner issues and troubleshooting techniques, including incorrect phase initialization, stability problems, discretization errors, and solver crashes. By addressing these topics directly, the course helps you develop practical problem-solving skills that are essential for real CFD work.
Every lecture is supported with complete, ready-to-run OpenFOAM case files, allowing you to reproduce all results step by step. In addition to the video lectures, the course provides additional PDF notes that summarize solver theory, modeling assumptions, and setup guidelines, making them useful as long-term reference material.
By the end of this course, you will be able to confidently set up and run simple 2D multiphase, phase-change, and multi-species simulations in OpenFOAM, and you will have a strong foundation to progress toward more complex 3D and real-world multiphase CFD problems.
