interTrackFoam
 

Hi
I am wondering if interTrackFoam in openfoam1.6-ext is correct and if it could be used to simulate die swell. Thanks.

Yes. It is correct.

Thank you for your reply. Could you tell me how do you confirm it is correct. Do you have any verified paper or you verified it yourself. In addition, do you think it could be used for die swell simulation? I have tried to do so but seems not work. I am not sure if it is because the solver is suitable for such simulation or because I set up the wrong boundary conditions. Many thanks.

You can search for the papers by the original authors of the code: Tukovic and Jasak. Also, the PhD thesis of Tukovic should contain a lot of information, but you need to learn Croatian first :)

I don't know what "die swell" is, but if you think it is appropriate, you can make it work.

I do have the papers by Tukovic and Jasak, but I think they did not make a full comparison with others work for one fluid situations. Die swell is when fluid flowing out of a tube, it will shrink or swell. When I was doing a such simulation, I find out that the flux phi at the outlet is increasinglly growing, which is nonsense.
