Hello!
I am looking to simulate a turbocharger centrifugal compressor for optimisation purposes, using OpenFOAM in the near future. I have not used this solver before as in my research I have used Ansys Fluent. However, I have read in some literature that this solver is used somewhere. Please if anyone has experience with this or have any recommendation or suggestion, it will be a great help.
Thank you
Hi Anglia,
I would say that OpenFOAM is a great software for your project. OpenFOAM's compressible solvers rhoSimpleFoam or rhoPimpleFoam are initially a good choice.
Regarding optimisation, OpenFOAM also has solvers to perform shape and topology optimisation which can be helpful for your application. Nevertheless, the adjoint implementation is not as straightforward as it can initially seem and currently is somewhat restricted to incompressible flows.
You can check the article from C. Othmer to give you a good perspective on the whole fluid mechanics adjoint implementation.

Hi Mario,
Thank you for your answer.
I also think that OpenFoam is a great software for my project and it is free of charge. Can you please forward further information about best way how to learn this software. Any information about tutorials or any free training would be a great help.
Thank you and regards,
Hi Kristaq,
Unfortunately, OpenFOAM is not straightforward to use, but its learning curve is quite steep in my opinion. The software itself has a very complete series of tutorials that can help you learn the basics.
Besides, most of the work done by the OpenFOAM community is usually discussed on CFD-online (https://www.cfd-online.com/Forums/openfoam/).
More specifically, I would highlight the work of:
Who fantastically spread the use and learning of CFD and OpenFOAM. You should definitely check their YouTube series about CFD and OpenFOAM.
Best regards!
