 * Note that this is an important simplification. Here we 're are considering that the turbine is already spinning independently of the flow, what which is clearly not true, since the flow is responsible for spinning the turbine. There is only one stable combination of incoming flow velocity and RPM, given the geometry and mass of the turbine. However, modeling the movement of a geometry caused by the flow is considerably difficult, and require requires the use of a method called "6DOF solver". A tutorial on that is intended to be made in the future. For now, let's stick to a simpler analysis, first a steady state picture of the problem (this tutorial), and later a transient analysis (part 2 of this tutorial).
