Wind turbine aerodynamics: Part 3 - Momentum theory, the Betz limit and wake rotation

This video will cover the fundamentals of momentum theory for wind turbines. The layout is as follows: First the video covers the Betz theory wind the axial momentum theory for the wind turbine. Then, wake rotation is added, with focus on what you need to implement the blade element momentum model. Finally, the optimal power coefficient will be derived within the wake rotation model. I want to give an acknowledgement to my collegue Marcus Berg, who have been of assistance in making this video 0:00 Introduction 02:54 Betz theory derivation 21:15 The Betz limit 24:08 Model limitations 26:36 Wake rotation 41:28 Derivation of optimal power coefficient with wake rotation 1:01:15 Final results
