No Slip Boundary Condition

[@4-1-19]

I only needed about 40 seconds of this video, but it helped a lot. Thanks :)

[@Feinebea]

I’m currently working on understanding how the tear film gets deposited on the ocular surface. This helped a lot. Amazing work. Thanks!

[@ravindrakhakural6757]

You guys are genius scientist.... thank you!!!

[@arjuntandon1000]

Your explanations were spot on! Bravo!

[@BorisNVM]

spot on, very cool video

[@donniedorko3336]

2:15 Okay I already love your style but also THANK YOU SO MUCH for this diagram

[@amitsaini821]

its just makes my 6.19 minutes. kudos to both of you.

[@michailtimanov1841]

Great video guys, keep it up! 💪🏻

[@zahraakhalife9150]

Great video! 😊😊😊

[@felipecasarin596]

Great Video, lads

[@xavierbolivar-hazboun1347]

You guys are fun. Thanks for that!

[@Emtrthree]

This opens so many questions in my mind great presentation and I hope yall succeed on your degree. Never had the will to go into pde and de to go study into fluid dynamics, sure is interesting though.

[@2BrokeScientists]

Thanks Thomas!! Good to know that you find the content interesting, let us know if you have any questions related to the videos or something you want to know about. We would love to discuss them or make a video on the same. Cheers and Happy 2019!!!

is the friction at the wall of the pipe, actually between this no slip, stagnat layer of fluid and the rest moving fluid? So actually the friction is not with the wall of the pipe, but with the non moving fluid at the wall?

[@jasminradadiya7396]

So in viscous fluid no slip condition exist.. right?? And what about ideal fluid? As ideal fluid assumed to be non viscous, there should not be exist no slip condition... Explain

[@EbboHima]

Thank you for the great video. Loved your examples.

[@sky..theeeeea]

Amazing piece 👏 excellent 🤩

[@shubhamhedaoo4281]

Keep doing the great work. Best wishes from my side.

Nice presentation

[@mohammedal-shebani6408]

Excellent illustration. keep going scientists [BIG Like]

[@pawankumar-ir1fd]

Question :Same usual problem , boundary layer on flat plate. so if we use mercury as a flowing fluid in that case there would be boundary layer phenomenon??

[@haroldwestrich3312]

Thank you ! FIRST question : Are you still Broke??? SECOND question : If there is no way to escape the "No-Slip condition" then why do we need to set that setting? Is it just in case someone creates a new surface treatment? That would be AWESOME for centrifugal pumps!

[@nushratnarina3927]

So is it like, if there was a pipe through which water was flowing for 20 years, would the water molecules at its surface be 20 years old? As there was "no slip" at the contact surface since the beginning?

[@2BrokeScientists]

nushrat narina great question! In short, the answer would be no. Because of turbulence in pipes, the molecules stuck at the surface would also eventually just be washed off.so they would be continually be removed. But if you had to assume smooth laminar flow then in theory yes those molecules could be stuck for a long time!

[@wizzardofozium8253]

@@2BrokeScientists If I had a system with an open rectangular channel of appropriate dimensions for smooth laminar flow that was slightly asymmetrical due to a perpendicular thermal gradient, would there still be no solvent exchange with the surface?

[@anirockshady8120]

No questions. Just Kudos on live examples which greatly helps a student to understand the practical probs than bookish language. Subscribed and waiting for interesting topics

[@createtheengineerinyou6921]

Is no slip condition due to adhesion?

[@2BrokeScientists]

Yes primarily due to adhesion

[@esmithaganesan120]

What is the difference between no slip boundary condition and viscosity?

[@dhruvapte9308]

Question: is coconut oil on hand relatable to the Leadenfrost effect? PS interesting video guy!

[@2BrokeScientists]

Interesting Observation. Although coconut oil on your hand does actually leave a residue so it actually "wets" your hand. Leidenfrost is more related to when you heat a surface and a water vapor cushion forms underneath the droplet

[@gtastories2286]

Sir one question: Does the viscous force always neutralises the pressure difference in pipe flow of constant diameter to form uniform flow?

[@2BrokeScientists]

Viscous forces are always present where there is a boundary. In this case if the pipe is long enough the velocity across the pipe will attain a final profile. It won't be uniform across the pipe

[@muzzammilahmad8687]

why sound produced when we put adrop of water in hot oil bowl but in vice versa it couldn't

[@muzzammilahmad8687]

well done bro... i hv a question

[@manojjp7115]

Nice bro...

[@whatisthis448]

thanks bro

[@mayanksoni4086]

Is no slip condition real or assumption?

[@2BrokeScientists]

It is real, fluid velocity is zero at the walls. To make it more clear, the dust on the window of your car doesn't wash way when you throw water over it. And the no slip boundary condition is our way of imposing this physical phenomenon to solve the differential equations.

[@Sam-rl6ok]

Thank you for the cntent which is really helpful. Also, thank you for not speaking Urdo as most of indian researchers do, which means only who speaks Urdo can understan them. Cheers :)

[@nurnajiihahbintishahimi9439]

your explanation is really good, but it would be great if you put substitles in it . Thank you 🥰

this is so cute i love it actually had fun learning about something !
