This PR has the implementation of the generalized actuator disk model (see Appendix of Mirocha et. al. 2014, Chapter 3 of Small Wind Turbines). Similar to the simplified actuator disk model, GAD also models the wind turbine as a disc, but takes into account the details of the blade geometry and the sectional coefficients of the blade airfoil cross-sections. The rotation of the blades are taken into consideration as well. See the docs for the details of the implementation.
Fig. 1 shows the x-velocity in the xz plane showing the wake, and the y and z velocities in the disk plane (looking onto the disk in the direction of the flow). The effect of rotation can be seen.
