21. Magnetohydrodynamics

Ғылым және технология

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/notes.html. They are really great stuff.

    I need a plasma toroid ball that will change its wave shape based on sound input FFT phase metering and change its colors like a polar lights. Is it possible to create such a thing?

    Grandpa was Lt.Col with a 66 military intelligence brigade WW2 Tasked with development and implementation Various frequency technologies Including Magneto hydrodynamics demonstrated in this video. I have witness 1st hand the full potential of this Technology that all but disappeared from public discussion. This education needs to be reintroduced into schools.

    @@DANTHETUBEMAN don't know if you're joking or not, but that is precisely the mechanism of action for the first anti-gavitation propulsion system developed by the US some time ago. The first paper on the subject was published in Scientific American in 1962 ;)

    Because public schools are designed to create a workforce that gets their knowledge from a curriculum, not from the results-based scientific method. "If everyone was an engineer or physicist who would shovel the dirt Mortimer?" That's why. It's the same reason why we destroy the source dipole with the same amount of energy we create it with in a generator; leave the source dipole alone and you can use the generated field to pull from the vacuum and produce "overunity" rather than that 35% coming out of your local power plant. Everyone who has created overunity fell victim to the banking cartels, and energy syndicates.

    ​@@nighthawkviper6791 a part of it is indeed learned at school. At least the deflecting effect from a magnetic field on a fluid (water most of the time). The subject is not studied deeper than that. It's because specialization comes after a minimum knowledge. You're not trained to be an engineer in schools. You're trained to basic knowledge you need to have. Of course the educational system is not perfect and the possible applications of MHD are too much disregarded. However application of MHD is well implemented in the industry, especially hydraulic pumps. MHD permits to save energy, lower frictions, enhance the pumps life in the industry. It's a well known system used for years. The debate of the usefullness of not of MHD is not for these industrial fields but is about the feasability of using MHD as a propulsion mean or wake turbulences or shock waves supression. One of the pioneers/fathers of MHD is a French former brillant aeronautical engineer. His name Jean Pierre Petit. He had a great role in the evolution of aviation with his works on aerondynamics with Cohanda. He is also responsible of the use of MHD in hydraulic pumps, but he claims that MHD can used for propulsion and shock waves supression, which is very controversial in the scientific world. Jean Pierre Petit was one of the most brillant mind in fluid dynamics science especially in aeronautical engineering. I'm a former private pilot.

    'in an accessible way' - near tautological phrase/word. 'as such' - Just say 'so' because it is one word rather than two. It's like when people say 'as per usual' when 'as usual' means the same thing. As such is just wrong in your usage too... it's used in maths lectures a lot. 'laypersons' - people is the plural of person. Persons therefore is incorrect (yes it's used however by quite a few). 'If anyone wants me to take them down'... you used two words when one word is all that's needed. God I hate people that write like you (especially because it's infectious to me). Now, once you've mastered thinking you can learn science.
