Doubts about vawt simulation
 

Hi everyone,i have seen some videos about the simulation of darrieus turibines and i always see that the angular velocity is a initial parameter, but how can i know if the turbine reach that angular velocity? the angular velocity should be a result, shouldn't it? in the papers, i mostly see that the result is a curve Cp vs TSR but I dont understand why, if i dont know if the turbine really reaches that TSR.
