Hello Everyone,

I am building a model to simulate the flow over an impeller. I need to identify the radial position at which the interface between the stationary and moving fluids should be for a moving zone formulation. I understand that the position should be far enough from the trailing edges of the blades so as not to interfere with the wake but not too close to the periphery. Any recommendations?

I found very nice schematics of the tangential and radial velocity profiles in the trailing edge region for laminar flow a pump in Centrifugal Pump Design by J. Tuzson (available through google books). This information is not quantitative although the schematics appear to be intentionally drawn well and somewhat to scale.

I admit that I haven't not fully done my homework as I do not have access to the appropriate technical books nor probably the time to research this as I would like (industry deadlines!). So any advice would be most greatly appreciated!
