Hi.
I am a newer for OF and I have been trying to solve turbo machinery problem, such as stator-rotor problem, with official version of OF, like v1912, but I couldn't get the solution yet.
I'm seeing many guys recommend the foam-extend.
(OpenFOAM-v1912 released
Mixing plane interfaces Openfoam 7.0)
But after failing in installation of foam-extend, I am just trying back with v1912. And I just found 'partialFaceAreaWeightAMI' expecting it to be like 'frozen rotor'. But it does not have any explanation.

Could anyone give me some comment about my problem?

best regard.

Hi,
is there any forzen rotor model of rotor-stator interface in OpenFOAM.com?
How can I couple a single rotor blade with a single stator blade but with different pitch angle?
Thanks,
WhiteW

Hi,

This is tricky question. There is something which I tried in 2015 but it did not work well.

That is available in OpenFoam-extended. It has bugs and it does not work well, based on Hrv Jasak. The point is I do not know he debugged it or not after 2018.
Please see this link: http://www.tfd.chalmers.se/~hani/kur...er_reviewd.pdf


For you other question for forzen rotor, check tutorials of SRFPimpleFoam and SRFSimpleFoam. You can find some nice stuff there. mixerVessel is nice tutorial for this functionality too.
Good luck
Ardalan

Dear Ardali,
thanks for your reply.
I found an implementation for mixingPlane in Foam extend version however there is not a frozen rotor model.

The SRF tutorials are quite interesting, however there is only one rotating region and so there is no need of interface between a rotor and a stator zone.
I checked the mixelVessel, there is the rotor-stator interface, however it simulates the full geometry, so there is no need of an approach such as the mixingPlane or the frozenRotor to average the quantities between domains interfaces.
The axialTurbine tutorial of foam extend implements the mixingPlane interface model. It is interesting however the slices of domains have the same extension, I'll try to test it on a different number of blades.
