how to simulate francis turbine and validate result

I have designed a Francis turbine runner, with empirical method. One of steps of designing is to draw meridional flow field in 2-D. I have solved this by using Finite Difference Method (FDM) then by combining with conformal mapping method, i got the 3-D shape of runner. I must do a test to check if this method is acceptable, experimentally or numerically. Since experimentally impossible 4 me right now, i choose the second : Using Fluent.
My Questions :
1. How to perform the simulation [boundary condition, turbulence model to be used ..etc] ? in order to get the power output and efficiency
2. How to validate the result?
Please, help me, every reply would be appreciated.
Thank you very much.

I started to work on Francis turbine design but i got stuck. Can you send me document to do the analytical design of runner. And can you explain me the FDM and mapping method you used. I couldn't draw the streamlines in meridional view.
Waiting for your answer, best regards...
