12. Fluid Dynamics of Drag (Part I)

This collection of videos was created about half a century ago to explain fluid mechanics in an accessible way for undergraduate engineering and physics students. I find that no other series of videos has explained the basics of fluid mechanics better than this one by the National Committee for Fluid Mechanics (those national committees gotta be good for something...)
As such, I have uploaded these videos here for the benefit of students and interested laypersons. I do not own the copyright and these videos were not made by me. If anyone should want me to take them down, I will comply without complaint.
If you want scans of the printed notes that go along with these videos, check out them out over at the MIT side of things: web.mit.edu/hml.... They are really great stuff.

these mit videos are the best in fluid mechanics learning. Thank you for uploading them !

Ascher Shapiro was a very gifted teacher.

Thanks Mr. Belmont

great video! Thank you for this upload

thank you for sharing the videos

In a thicker viscosity a greater surface area produces more Drag, a dimpled golf ball will gain more lift than a smooth one. I'm sort of stumped on the bomb versus ball but would venture to say due to a unequal balance of pressure...

[@steve-o6413]

A fishes body reminds me of the bomb shape only difference is that it's flat instead of round. We can learn a lot from Nature's design of Birds and Fish in fluid dynamics...

bro where did you get these from

[@davidbain701]

So the shaking you experience in a flying in a commercial airplane Were the dominant flow conditions in the atmosphere Has altered ( pressure drop etc ), to affect stable flight speed Has the plane reached the speed were the smooth surface of the wings and body now has more drag ( But why did not the plane shake earlier in the fight When passing over the speeds were the smooth surface experiences this greater drag? )

[@belacickekl7579]

The shaking in commercial planes is due to large-scale eddies in the atmosphere, not necessarily rapid changes in the airflow over your plane's surfaces.

thanx for these videos

How can i get substitles?

Abla mezun olmuşsundur şimdiye

Matters look complicated.

[@peterbrune598]

So the drag goes down roughly at... RE = 45 m/s * 0.1 m / 1.5e-5 = 300000. Yup; that's the ticket.
