Description and Derivation of the Navier-Stokes Equations

[alexanderhasenclever]

This video was more useful than many hours of lectures at the university. Thank you!

This is marvellous. Why doesn't every class have a professor like you, no class would ever be boring...

OMG, this is the first time of the past 10 years of learning that I could understand this so intuitively! A big Thanks to you Sir from Shanghai!

I love when a professor doesn't skip the details.

This video is actually really good, and I am studying fluid mechanics in french.

I really appreciate all the efforts you have put in this, I can really tell you put a good amount of time into this.

Thank you so much.

Thank you so so so so much. I’m taking an aerodynamics course and between the textbook, professor, TA, and two tutors, nobody could give me a straight worked out derivation. I’m sure the professor knows it, but just couldnt articulate it. I dont understand how Anderson thinks you can skip 90% of this and still call it a derivation.

I've never left a comment on any video - but this is amazing - thank you so much!

Thanks for spending the time to create this content! It’s appreciated 🙏🏾

Thanks for uploading quality video which makes Navier-Stokes derivation approachable.

[DrCalabaz]

It took me 2 years to understand this. Thank you very much for this.

Bravo! I did mechanical engineering and am here for a refresher, this I am sure has never made more sense to me as it does now, and I enjoyed it.

Bro, you are a lifesaver. I'm currently using TELEMAC 2D, but I felt kind of guilty bc I didn't knew what the software was doing. Love you bro.

Thank you, very well explained. Hopefully now the derivation in my textbook will be a bit more clear to me.

[joshuachang]

Beautiful video, thank you for an explanation better than one a any textbook or human can give.

[adhavankadhiravan]

Excellent. What a clarity in your explanation!

[metallothionein]

Very helpful in understanding the various components of fluid turbulence. Thank you for putting up this derivation!!!

[prafulborker]

Superbbbb lecture....Simple and Admirable

[sajanthapa]

One of the best explanation :) .. Thank you Dr. Knutsen :)

[kent]

thanks for the video. Have you thought that the reason that the Navier-stokes equation fails in turbulence is that it is based upon elastic collisions (conservation of momentum and energy) when in fact the collisions are inelastic: see my recently published paper in engineering journal: google "EJERS" click on "archives" click on "Jan 2020" and my paper "illusions of elastic..." is near the bottom of the ;list, by Kent w Mayhew

Thank you very much kind sir, this video helped a lot. Greetings from Czech Republic
