Rotating cylinder with fluid
1 Attachment(s)
hallo,
I need to do fluid simulation in Open Foam which I uploaded sketch.. in sketch I have one round drum which filled with fluid half and half is air (multiphase) and drum rotates in its axis. so which type of geometry should I use? hollow cylinder or solid cylinder? and how can I give rotation to drum? does it change the mesh? I thought to use VOF method to create fluid in cylinder as in (dam break Example) in set Field. so is it right? please guide me further or if anyone has same case then kindly upload it . thanks |
Quick answer: Have a look into the "tutorials" folder, namely in the sub-folder "multiphase/interDyMFoam/ras": https://github.com/OpenFOAM/OpenFOAM...terDyMFoam/ras
Run the "sloshingTank*" tutorials and "testTubeMixer" tutorial and study how they are set-up. |
thanks for reply but i need round cavity instead of square or cube.
so how can i give patches? |
Quick answer: In the same tutorials sub-folder I mentioned, there is another tutorial named "mixerVesselAMI".

thanks.. i looked at this tutoriial also.. but i only need small roatating drum not whole mixer and i want this drum rotate itself.. so i have also STL or block-mesh file of cylinder
but i am sufuring difficulty to create fluid like damBreak so if you can guid me further it would be very helpful |

hi..i am trying to run multiphase/interFoam/laminar/damBreak example with changing geometry rectangle to round cylinder .. i did block mesh with cylinder patches -- works
but while simulation it gives error.. i am uploading my case , please try once and tell me problem.. thanks . as i need same dam break example with change geometry..:) |
Hi Dhruval,
Sorry, I was in a hurry the other day (still am today as well) and had hoped you would have tried to look into the other tutorial folders as well. The tutorial I had in mind was in fact "mixerVessel2D" and not "mixerVesselAMI". One such tutorial is "multiphase/MRFMultiphaseInterFoam/mixerVessel2D". As for the case you attached, there are a few problems that I can see:
Good luck! Best regards, Bruno |
