By Henrik Bredmose. This session is about power, thrust and optimum rotors. Here we will look at 1D momentum theory for wind turbines. Explain how the flow is broken by the turbine and the theory behind the optimum power production of an idealized rotor.

Very clear and direct to the point explanation. Congrats for the video and content.

A precision explanation of theoretical concepts based appropriately in empirical laws. It's the most useful application for practical purposes.
An Experimentalist's initiative response might be to analyse the data comparing incident flows and resulting streams of turbulence.
Interesting research projects.

Very well explained. Thanks a lot. Warm greetings from Perú 🇵🇪

Amazing explanation! Thanks Henrik

Thank you sir.. We are benefitted your lecture from Bangladesh ❤️❤️❤️❤️

Thanks a lot for ur clear explain

In the rotational æffexcts does rhe middle toggle or move forward or back?
When the wings come up would it be heavier if one out of three wings retracted inside itself? When it drops ut creates more umpf ?
How closely related is the carasel or ferris wheel?
What about the fan boat? Also the boat with barge boat? The one that pedals water all the way around the wheel ?
How many different ways can you agitate water without it becoming agate? If agate isnt open is it aggitated or an agrite possibly an augmentation?

Betz law is so simple to beat I am surprised it is a law at all regards Graham

[@grahamflowers]

Betz law has been smashed and debunked regards Graham
