Default Mixing tanks

I need some help with a simulation of a mixing tank. It is a mixing tank with some wall jets on one side and there is a hole in the bottom of the tank. I have used k-e and RSM for the simulations but the model does not agree with the experimental data. It does not spin around the hole as observed in the experimental. Any idea of how I can change the model for simulating correctly this swirling flow around the hole.

Thanks a lot

Is your mesh enough fine around the hole?

Yes I think so, although I can try to refine it more around the hole. The main problem is that water flow almost directly towards the hole instead of swirling around it, as I measured during the experimental work. I was thinking that maybe I should change the bc at the outlet. Any idea?

Thanks a lot!!!

When you compute some pathlines, what do you see?
