Hi
Anyone has experience with Turbomachinery CFD that is based on Openfoam modified for simulating turbomachines?
As far as I know, it has some advantages like robust solver for turbomachinery, automated process (workflow) (which I dont know what is it!), and specific boundary conditions for turbomachines.
I wanna know I can download the software for free or not? (like openfoam that is free)
Or any tutorials?
Thanks a lot if you share your experience with me.

Hi Ram,
I was working on turbomachinery problem with OF2.1.
Though the version is changed, I dont think the process is completely changed more or less it will be same.

Regarding tutorial, I have one, I will check it.

Please mention clearly, which area you are looking for help.
Please raise your question clearly,


Thanks,
Sivakumar

I have read that another software which is based on Openfoam is stronger for turbomachinery and is modified for this purpose:
Turbomachinery CFD
I want to know if you have experience with this software, and if I can download it free like openfoam.

In your case, was Openfoam strong for your simulation? I wanna simulate 3 different turbines, what kind of turbo-machine was your case study?
Thank you very much in advance.

Hi Ram,

I presume that you are talking about SU2 (I have no Idea about it). In my case I used OF for my Axial Flow Fan. OF was good enough even better result than Fluent (I am not that strong in Fluent).
the drawback of fluent is that, you can not understand what you are doing ( you will select from drop down list).
but OF it will be difficult in the beginning after some experience you will be fine.

my suggestion will be go with OF, if possible I will help you some extent.


Thanks,
Sivakumar

Thank you very much, I need just hints to start. If possible please send me email:

I hope I can find the first step, I appreciate for your attention.

Hello Ram,

I do not have any experience on this "Turbomachinery CFD" software you asked about either, but maybe you can have a look at the Rotating Machinery training by Hakan Nilsson:

http://openfoam-extend.sourceforge.n...s/courses.html

Foam-Extend, a fork of OpenFOAM with different community contributions is used there.

Best regards

Andreas

Hi Sivakumar

I see that you have used OF for axial fan flow and achieved good results. In my work I am trying to model a turbine stator passage using rhoSimpleFoam. However I do not achieve good results. Previously I have used Ansys CFX and got good results in comparison with experimental data. But my OF simulation does not achieve the same results, underestimating the upstream pressure (velocity inlet and static pressure outlet).
Do you have any advice?
