If you want to know the RPM of the turbine with a given head and discharge flow then sorry Flow sim does not have this capability,
Ty for the info. How about getting the torque applied on the buckets?
Actually there is a way of doing it:
Set up your Pelton wheel model, and use a rotating region to encompass it. You'll need to use a transient study (Time-dependant).
Set up a surface goal for torque and then select all of the faces that you want to evaluate the torque on (Then torque times rpm is power consumed).
Set your discharge flow and head up as outlet and inlet boundary conditions, respectively, and set up surface goals for each of these. Set up your rotating region at a sensible speed (Just your best guess will do fine for now).
Then you can do a 'goal optimisation' which falls under the parametric studies menu. Set up rpm as your goal to optimise (Target should be set as 'lowest' or something similar) and Solidworks will work out the lowest rpm at which the Pelton wheel can achieve the flow conditions.
Personally I use lots of equation goals (Things like pump developed power (Pressure x flow rate), pump consumed power (Torque x RPM) and then efficiency and so on.) so that I can output the results to excel.
Have a play with this and let me know how you get on, I do this with Centrifugal Fans all day long so can help.
Hope this helps,
