Hello,

I am currently working on my BSc final year project which is "Designing and Analysis of Gravitational Vortex Turbine ". It is a 3D model having a conical pool in which vortex forms and NACA0021 blades are used in the rotor. I am using RNG- swirl dominant flow with scalable wall friction. I have selected periodic relation between walls.
I don't know how to calculate the Cp (Power coefficient) of the turbine. I will be thankful if someone could help me.

Thank you

In results, no streamlines are shown in the pool even I have selected variable option but a scale showing maximum velocity is visible.
