Following previous post about SRFSimpleFoam, i conclude that it's not perfect solver for simulations

Also i have had many problems with stability and convergence. Not in this simple case but in case of rotating blade.

I've found interesting article about experimental investigation of a rotating diverging flow.

There are a good data about geometry and results so i decided to conduct simulation in SRFSimpleFoam.

what i have for 30 rad/sec and Re=15800 (3m/s at inlet)



The coincidence is pretty good but not perfect. Data for 60 rad/sec is coming soon.

I met one big problem when i have converted SALOME mesh by UNV format and ideasToFoam utility.

It was not usual mesh, it contained pyramids. See fig.



I spent a lot time to achieve the same result like i can using ICEM. Only when i've found salomeToOpenFOAM script i successfully converted my mesh.

So i recommend it. The script is very helpful.
