Angular velocity in wind turbine simulation

I want to study a new wind turbine with vertical rotational axis.
I think, on the base of the shape of the rotor, that a sliding/dinamic mesh is necessary and I would like to start with a 2D simulation.
Obviously I donít know the rotational velocity of the rotor at a specific wind velocity.
I think that I must take into account the torque and power necessary to generate electrical energy.
The question is how can I setup this simulation? How can I make the flow to move the rotor?
I think to use this formulation for angular velocity ω that must be applied to moving/sliding mesh by an user defined function.
ω t = ωt-1 + [Maer t-1 - M res (ωt-1)] / Irotor * Δt
Maer= torque calculated on rotor due to flow
Mres(ω) = function for torque due to electrical energy power generation depending on ω itself.
Irotor = rotor Inertia
Do you agree?
Thanks in advance
