But we're not done! To calculate the TSR we still have to perform one short step. Recall that TSR=veloc blade/veloc wind, so all we have to do is divide the calculated velocity by 10m/s, the wind speed.

So, our TSR is 0.01676. We will use this value to estimate the value of Cp.

compare blade velocity (TSR?)  This is a BC, so it will essentially just check whether we had inputted the correct mathematical model into the tool.

Verification

Compare Cp with the expected

mesh refinements (different mesh. Summarize, don't need to show steps) Cp might be bad, refine the mesh and check.

 

Validation

check against FDRL data? Might have to re-scale, as it is a little larger, flow max at 7m/s and much greater rpm.... If you scale it up to xxx this is the results you'd get. Compare Cp, try using the actual wind speed and angular velocity.

 

Actually the angular velocity is coupled with the incoming velocity. To capture that with fluent, we would have to use 6DOF which is too complex. So a trick would be..... see jeremy email.

Mesh Refinement

Make a test refining the mesh (provide geometry?) and check reduced mass imbalance, check change in plots?

 

Maybe making geometry with actual airfoil? Scale up?
