Hi everybodyand happy new year;
I'm trying to simulate a two balded wind turbine in a lateral wind....( yaw position). in this case, wind is not purely axial and then the behavior of the two blades are different.
When one blade is going to the wing( advancing blade) , the other is rotating in the opposite direction( retreating blade). Then, every thing about the aerodynamic forces depends upon the instantaneous position of the blades and every thing will be unsymmetrical.
now my question is that can you please help me how to simulate this kind of situations?

thank you in advance.
