Hi All I am involved at a r
I am involved at a research group that would like to simulate an impeller working at the surface between two fluids (air and water for a start). This is a mixing vessel application.
Is there a standard OpenFOAM solver that makes use of a VOF formulation with interface capturing, allows for rotating meshes and makes use of a RANS turbulence model? k-omega preferred. Explicit temporal discretization will also be needed.
Apologies if this is a question with an obvious answer, from the lists of solvers I cannot quite determine if the above combination exists.
No, it doesn't exist. It ought
No, it doesn't exist. It ought to be possible to combine elements of rasInterFoam and turbDyMFoam to do this, but I suspect it might be quite tricky!
Hi Chris, I recently set up
I recently set up a model of a mixer with a partially immersed impellor. I had to get the 1.5-dev version and recompile as the rotating mesh with ggi interface is quite broke in the standard 1.5 release. The solver I used was interDyMFoam (Gavin - the solver for this problem does already exist - it was that that the correct mesh topology library was missing).
I only used the k-epsilon turbulence model but it appeared to work ok. Not sure about some of the standing wave formations that form on the rotating mesh part - I want to run some 'basic physics' tests of my own before I put my name behind the results.
Anyway, I can post my model and a description of how to run it tomorrow if you want.
Thanks Greg - thats quite inte
Thanks Greg - thats quite interesting as I may need to use something like that myself!!
Greg So this is possible an
So this is possible and I can live with k-epsilon if I need to.
The sad part here is that I know NOTHING of OpenFOAM and need to install it first and get started. It is however important for me to know that this is possible before I commit to spending the time to get into things.
I would appreciate it tremendously if you could post the info for me, although it might be a while before I get to actually use it. In fact, it seems that the problem has shifted from just a mixing vessel to something more like a flow-through system, i.e. inlet and outlet regions will need to be included as well.
By the way, will this run in parallel?
Another question: do I need to go for OpenFOAM training or would I get along by just following tutorials and, in the event of crisis, cry like a baby until somebody on the forum pities me and helps me (or helps just so that I can stop irritating them).
