AMI turbine application
Hi all,
I was wondering if it is possible to define a case with AMI patches, like the one on the propeller tutorial, where the rotational velocity is calculated. Much like a turbine, where the angular velocity depends on the velocity of the flow. Thanks in advance. |
Hallo Onyir,
I have tried simply to use instead of the "rotatingMotion" contained in the tutorial (tutorials/incompressible/pimpleDyMFoam/propeller) under constant/dynamicMeshDict, the keyword "oscillatingRotatingMotion". As indicated in the source files "oscillatingRotatingMotion.C" and "oscillatingRotatingMotion.H" one should use within dynamicMeshDict the following: Quote:

Hallo again,
I've tried with a simpler model also contained in the tutorials (tutorials/incompressible/pimpleDyMFoam/mixerVesselAMI2D), and with the little modifications to dynamicMeshDict it works fine. I can not attach the folder from one can run the case, since it is a bit bigger than the forum upload file limit. If you need it send me an email. Hope it helps, Elia |
Thank you for your interest fakekarma, but what I want to achieve is that the motion of the turbine is driven by the flux, more like the tutorial of moving wing, not by specified rotational speed.
Regards, Ricardo. |
Hallo Onyir,
I can not understand if you need your body to react to the flow (like in a 6DOF simulation) or just have a variable speed based on some probes for velocity. In the last case you could modify the source to accept an input for the omega instead of a fixed value. Cheers, Elia |
Hello,
I need my body to react to the flow, like a 6DOF simulation. Sorry if my description was not clear. |
Hallo Onyir,
as far as I now, the 6DOF capability is implemented in OF 1.6-ext, where user can set inertia, spring and damping parameters, that would be used in connection with the force and moments to etabilish the motion of the body. I've taken just a very rapid look to OF 2.1.0 and it seems to be no more present. Good luck, Elia |
