16. Cavitation

[@nkntr]

It is so important that videos like this one are kept around for folks to view and understand. And yes, there are actually people out there who LIKE seeing and understanding stuff like this, and will waste time on a Saturday just to watch and understand a little bit more about the world around us.

[@Rhino011]

you are right. The self study of cavitation and other science reactions is very important to keep the young people interested in studies that really matter. The study of cavitation is what make our nations nuclear submarines quiet.

[@tonybarber420]

Morris Stevens yes that's me! I love when I find videos like these, or rather when videos like these find me. I wish the whole of society were interested and only cared about important stuff like this

[@zeroswings2]

I'm one such person 🤣🤣

The best way to explain the basics of fluid mechanics.

[@mogmogman5476]

Thanks for posting this on KZbin. Seems to have come from 1963 era. Science was taught quite well in my day and this proves it. Have downloaded this to the science library of MOG Canal Boat, the Totally Electric Powered Solar boat.

[@dannz2603]

Yes this is a very good explanation of cavitation and I have learned some things that I hadn't previously fully understood, thank you.

[@davedonovan2681]

The most informative video i've ever watched on the subject. Incredible.

[@AndyDaviesByTheSea]

If you’ve seen the old film ‘The Time Machine’ you’ll have seen how all of the old wisdom was stored on spinning rings. Let’s hope we never lose sight of the wisdom stored on our spinning discs. Thanks for posting. Kind Regards . . . Andy

Wonderful video!

[@RedRouge361]

Excellent video ... Seeing is understanding !

[@hellbrokelucy9686]

17:45 Significant weight loss has already occurred? Screw treadmills, I need a Magnetostriction Oscillator.

[@Nik-ok9nu]

This is super fascinating stuff! I wound up here trying to make my performance boat faster! 😁 Thank you for making this available!

[@bthnt]

Excellent! those old-timey scientists really knew their stuff.

[@anilsharma-ev2my]

We called vimana which shows differentiatial between two values so we can go anywhere in universe So powerful aspect of all the problems regarding go through it We acquired that values which shows the meeting point of two extreme and make a path parallel and equally distance between it's two extreme values Vimana shastra entirely depending on this aspects Different between two values of upper and lower limits of force ???

12:30 Lift and drag change of the foil as caviation grows 15:18 Shock wave generated by the collapse of caviation bubbles

[@flybobbie1449]

I just assumed cavitation is simply ripping the water molecules apart. What is inside bubbles, steam? We would get cavitation inside hydraulic pumps, would make a right racket and pressure would collapse.

[@suomik1988]

This is so cool. Now I can do my homework!

[@505197]

I amazes me what scientists can figure out and how knowledge is built up in layers. Astronomers had to make lenses, invent the telescope, look at the heavens and build the entire science by hand more or less. This eventually led to the Hubble telescope floating out in orbit, If Galileo could only see us now.

Thanks

But a small area means more pressure as P=F/A....then how does the pressure decreases with decrease in Area..

[@rextsou4207]

In flow path, when flow area decreases, the velocity will increase which will decrease the static pressure. Furthermore, higher the velocity will cause more pressure loss due to friction or internal dissipations. When the static pressure is lower than the vapor pressure, the local boiling occurs causing cavitation. The equation P = F/A is not relevant here at all.

[@laprepper]

This video was more interesting than almost anything I did in fluid dynamics.. :/

[@malleshiitm]

A nice video, thanks for uploading. can u please share the material?

[@jaycal1920]

Its funny videos like this dont go viral... imagine a world where they did. How advanced we would be.

[@miladyusefi2529]

how I can find a subtitle for this movie?

[@peglegnoid6139]

[@shaider1982]

Here I was thinking that CFD pictures were cool. Nothing like the real thing!

[@rodrigoevaristosilva7790]

Zona de recirculação é onde a velocidade é negativa.

[@Mech.Masters]

I have learned in a textbook that cavitation in turbines can be reduced using runner of low specific speed.....Does anyone the physics behind this? Please help.....

[@rextsou4207]

This can increase the local pressure a bit, making it above the local boiling pressure to prevent cavitation.

[@boogerisapain]

no sound?

[@johnjohn-wc8fz]

26:30 very interesting

[@Twizt3dArc]

I find it interesting

[@u571lxx]

great staff!

[@bosskier878]

this movie blows, only here because my professor is making me watch it

[@davedonovan2681]

sad that you dont appreciate this. it's a lot more fascinating when you think about the fact that people trying to break sailing speed records upwards of 80mph are dealing with such issues like cavitation.

[@adenmhed7924]

Great video !
