Hi everyone,

I am currently working on project to develop a CFD model of a pico hydro turbine using ANSYS Fluent. As seen in the images attached, I have decided to isolate my component as I only want to run the CFD analysis on the turbine propeller to improve its design efficiency. Currently I have managed to create the model geometry and do the meshing but I have certain issues with the setup. I have used this link https://www.youtube.com/watch?v=KFrZoDWUC5s as a reference as my turbine is also axial flow but uses water instead of air so I am not so sure with regards to the Boundary Conditions settings. I am also not sure if I am about the correct steps and would appreciate any inputs. Please advice if I am in the right direction.

Problem :

1)How do I do my settings for my setup ? (Frame motion and etc ?)
2)And what are my boundary conditions to select ?

Facts :

1. Low head turbine (using 1.5m head)
2. Water velocity = 3 m/s (average by calculation)
3. Water flow is based on gravity (no pumps or etc, can be seen from the image attached)
4. Power output from turbine 1 kW

Thanks in advance for taking your time to help me.
