Hello,
i was wondering if one can give me hint on how to couple a volute with a stator-rotor simulation. MRF with just a stator and a rotor works perfectly fine. Adding just a section of a diffusor works as well but as soon as I add the volute to the simulation i get a segementation fault error. I guess its due the fact that SU2 tries to find spans in the volute. Even though if i define it as a general fluid interface. Is there any possible to couple a turbomachinery simulation with a general volute, as there is no option in SU2 turbomachinery kind, for a volute. Set up:
EDIT: I looked a bit through the source code and tried to understand how the solver is handling turbomachinery. If i understand it right, the problem lies in the assigning of turbomachinery kind to each zone. I have not yet figured out, how to avoid to set an turbomachinery kind to one zone, as setting "NONE" is not a valid option. best regards, Lorenz

Sadly, I have the same issue and I have not been able to figure it out. I may just remove the volute part. Ashvin |

Hi Lorenz,
At the minute the turbovertex structure is built between two periodic boundaries (see this paper https://arc.aiaa.org/doi/epdf/10.2514/1.B37685), I assume in your case with volute you do not have periodic boundaries, and model the whole volute? This is a requested feature by several users but at the minute I don't think anyone is actively working on it. In my opinion you have two options - 1 - Implement the modification of the turbovertex structure to be able to build the required data structure around a full annulus rather than between two periodic boundaries 2 - Model only half the volute and use periodic boundaries I would encourage you to attempt option 1 and there are several developers who will be able to assist with this, but option 2 could work fine for your application. |
