mazhar16823 is on a distinguished road
I have taken three-bladed HAWT; But in the simulation, I am modelling the flow around one wind turbine blade by applying periodic boundary conditions using STARCCM+.


I created a report for the moment coefficient, that shows the data for Cm was stored at each time-step until the end of simulation. After which I ran the report to calculate the Cm. Now, I want to calculate the Cp, for which I use the formula Cp=Cm*TSR is that a correct way or I shouldalso multiply it with 3 considering three-bladed HAWT? If I do so, the Cp is unacceptable, however if I just use Cm*TSR it gives the Cp in a good range.



Secondly, I didn't create the report for thrust coefficient during the simulation. Is it possible to calculate it post-simulation and how?


Thanks for your time. Your answers wil be highly appreciated.
