About FOAMY Lectures
Hello. This is Cüneyt Sert. I am a faculty member at the Mechanical Engineering Department of Middle East Technical University (METU). I have been doing Computational Fluid Dynamics (CFD) related research for more than 20 years. My current research interests include
- Adaptive hp finite element solution of flow problems.
- Microflows inside rough channels and pipes.
- Flow generated acoustics in stenosed blood vessels.
- Numerical modeling of ablation due to aerodynamic heating.
- Simulation of regenerative cooling in liquid rocket engines.
Actually the web is already full of teaching materials for OpenFOAM, mostly in the form of videos. Some of them are great, but they are a bit disorganized and can be hard to find. And some of them them are outdated. Like most CFD tutorials, including the official ones prepared for commercial CFD software by their own developers, the ones for OpenFOAM mainly focus on the “use of software”, not on the "correct solution of the problem". Their main concern is how to use a specific software to solve a specific problem. How to generate a mesh, how to solve the equations, how to post-process the results. But in all these steps you can use the tools in the right way or the wrong way. It is much easier to generate wrong results in CFD than the right ones, especially if you are inexperienced. It is not uncommon to see poor CFD practices in the video tutorials that you can find on the net.
In these lectures, we will be concerned by the following two points, the first one being more important than the second.
- How to do correct CFD?
- How to do it in OpenFOAM?
One of my plans is to make use of my own research and include that experience in these lectures as much as possible. In doing this I'll make use of our group's work in the field of vascular biomechanics, microchannel flows, vortex dominated aerodynamic flows, large eddy simulations, etc.
The very first lecture of these pages was created on 26 June 2019. New ones will be uploaded as they become ready, but unfortunately my progress is a bit slow. If you want to give any feedback or suggest corrections, please send an email to csert AT metu edu tr.
