great video but at around 6:44 why is RAx = 0 ? the support is a simple (pin or hinge) not a sliding simple support

It's sad you guys replaced this course with another version. This one was much more in depth. I left coursera, came back some time later and it was gone ): .

Hello, the data avaible for annual mean wind speed is between 200*-2017 only. Is there a any way to get an updated one? particularly 2019 to the present?

No. It is not. Sorry to say. From 1:30 we just skpiped and didn't mentioned skin effect. At 5:28 the cirkuit diagram is a .... disaster. Is there any electrical engineer here?

Prof Sorenson, Thanks for a great derivation of the Betz limit. However, I am struggling to understand something - In the control volume analysis slide, in the axial momentum balance, you have a term -mout*U0 representing the axial momentum of the air going out of the domain, ie the red top far-field boundary. I am guessing that the velocity here is (U0, v, 0) where v is a small y component, without which mout =0. Sam

I got the concept, awesome idea to show the forces on the blade, thanks❤

@tapiopohjalainen3799 5 ай бұрын

Almost correct and maybe the math gives correlation to energy withdrawn from the wind. The correct idea is that the energy is proportional to the area of wind blades rotational area (disc) and the reduction of wind speed. That is the true reason it gives energy. It easy to understand that the mass the wind turbine handles id the area of the disc multiplied with incoming wind speed. m=A*v(wind speed)*roo (The density of air). m^2 * m/s * kg/m^3 = kg. F=ma a = deceleration of the air mass handled. Some of the energy is lost because of the rotor efficency due to friction which is mainly released as air vortex. At these speeds the temperature change is minimal, except maybe at the blade tip where local air velocity is approaching to speeds where air is compressible, close to the speed of sound. Power in wats, W = F/dt.

Hi thanks to all for your knowledge... I'm working in the wind turbine blade manufacturing industry in the quality department so I have lots of questions My 1st question is that What is the difference between Unidirectional, Triaxial and Biaxial glass fiber? What is the difference between Pet core, balsa and PVC? Why different locations are using like some location only bx or some location ud whatever why?
