Turbulence Model for flow between corotating disk
Which turbulence model is recommended for the following case?

Flow between corotating disks, specially attention that the gap is very thin

b << r (b=gap, r=radius)


ro/ri=6, (i=inner, o=outer)

Re-b= 30 (reynolds associated to the gap and circumferential outer tangential speed)

Re-l = 6500 (local reynolds local at circumferential station associated to the radius and tangential speed)

One similar model can be visualized in the following page Just to have into account that for my case is a open system in which the flow enter at the pheriphery and exhaust at the inner radius.

What about damping from Low re ke to High Re ke Models? I mean : two simulations -one with high Re and other with low Re ke-, or two regions of the flow an inner and and outer. I am using fluent.

I thank in advance for the suggestions and opinions.

Best regards Felipe Rey
