Tutorial to help tank sloshing modelling (CFX 12.1)
Dear Friends,
I need to model tank sloshing. I want some tutorials tahat could help me on this modeling. I'm using ANSYS CFX 12.1 Thanks for all your help |
Hi Hamed,
I dont know if there is a tutorial for this. May be I can help you with some stuff. post your questions. I try my best to reply them. Thanks Nelly |
The free surface flow over a bump tutorial simulation is the best tutorial on free surface flows.

Hi all, am new to cfd-online.
I also am trying to develop the cfd model of liquid slosh in a tank (shape not specific). I would like to do this in Ansys CFX. I just need the CFX part of the work & I am able to model the geometry & mesh it using moving-mesh technique which is I think the most suitable mesh form. I am pretty unsure of how to do the CFX part because no tutorial or data I got from internet speaks about slosh modeling. Any cfd-specialist can help me?? |
Look in the CFX tutorials. The "Flow over a bump" one shows how to set up free surface flows.
|
ok, will try
Thanks |

Can you please help me how should I apply the moving mesh? What kind of equation should I specify for the moving mesh? Regards |
i am studying that now. anyways it has to be done using the VoF method for satisfactory results. i'll post here on how the mesh is made dynamic soon.

hay if you has link or file pdf about modelling sloshing.... please upload them ;)
that great idea to make our tutorial so we can easy to get tutorial on future |
Hey, Hareesh, I have been working on fuel slosh simulation using CFX for my thesis. I am working on developing active damping mechanism for fuel slosh. I have been able to simulate fuel slosh without providing moving mesh. Volume fraction is the important factor for obtaining free surface. However, I cant figure a way of measuring the amplitude of fuel slosh in my simulation. Can any one suggest a way to obtain the amplitude of the sloshing in CFX.
Thanks |
Sloshing and global motion
how to synchronize motion of ship and sloshing??
i am confused about that.. any one can help me??? |

There's are some ansys 12 tutorial slides with a transitory case with tank sloshing somewhere... also, for the free surface it's common to assume that the isosurface where the volume fraction is 0.5 is the water/fluid surface.

friend, the tutorial procedure is for 2D, the same procedure is valid for 3D
