Hey everyone,

I'm trying to model a tesla turbine (a number of flat plates close together with a inlet velocity in the radial direction) in FLUENT, but I'm not quite sure how the RBM works out. The FLUENT manual seems to imply that I have to give FLUENT the rotation speed and whatnot of the turbine - but I want that to be found in the solution; the flow has to make it turn. I'm not quite sure what to set up in the profile.

Essentially I want the turbine position pinned, but still allow it to rotate via shear stress from the fluid. Can anyone offer any help?
