In this presentation, we study various aspects of the wind turbines or wind mills. We optimize the performances of both a single wind turbine and a wind farm, collectively. We study the nozzles on the blades and all the variations and accessories for the operation of a nozzle. We also explore flow patterns around the blades, the mechanisms to get air or other gasses to the blades, the couplers for the electrical connections and the gas connections, and the gaps, holes, channels, conduits, or openings on the body or structure of a tower. We also present various mathematical models and formulations for optimizations.
