Rotor - stator how to create mesh?
1 Attachment(s)
In this thread I used the boundary condition rotatingWall for bottom of cylinder filled with liquid. But now my task a little harder. I need to create an edges at the bottom of the cylinder. Like on the picture.
In this case, the bottom together with the edges should rotate. Can someone help or give links to related tutorial? As I understand, I have to use a rotor and a stator patches. How to do it? Or may have another way? I apologize for my silly drawings and terrible English :) |

I'm not sure if it possible in OpenFOAM, but I would just assign all the members to the same patch and assign rotation. Just a first idea which came to my mind.

Yes there is, just go in to the RasProperties file and switch it off. |
Hey,
do you know how the Coriolis Force is implemented in MRFSimpleFoam or in OpenFoam in general? I cant find the file. the equations i got from OpenFoam Wiki include the Coriolis and Zentripetal force, but in the MRFSimpleFoam.C file it is written that they just add the Coriolis term. Thanks Sarah |
Hi Sarah,
I thinks its a little hidden in the MRFZone.C file. Within the member function there are two overloaded addCoriolis functions (in the internet doxygen it's line 294 ( void Foam::MRFZone::addCoriolis(fvVectorMatrix& UEqn) const) and 315 ( void Foam::MRFZone::addCoriolis (const volScalarField& rho, fvVectorMatrix& UEqn) const). If you click on the Foam::MRFZone::addCoriolis it is linked to the doxygen. Hope this helps Kathrin |
