What is viscosity? Viscous and inviscid flow.

Welcome to another lesson in Introduction to Aerospace Engineering!
In this video you will learn what viscosity is and what is the difference between viscous and inviscid air flow.
Let me know what you think of the video in the comments and subscribe to my channel to stay tuned!

How much more viscous is honey compared to air?

[@satyapratapnayak4853]

Viscous of 🍯 is 1,00,000 times the viscous of air💨...

[@Sondus-yu5hl]

but why the viscous effect can be neglected in the inviscid zone?

[@AliyaBurkit]

Because the gradient of velocity change is not as big as compared to high velocity.

[@sagarsonu9565]

10000 times as per the video and what if the no slip condition is not taken in account what will be the senario

[@AliyaBurkit]

That's a question for a separate video))

[@teruelryanpaul]

I cant express how grateful I am for these videos

[@AliyaBurkit]

Thanks so much!

[@Uniquecapture]

I love the simplicity of your explanations. Where were you when I was at uni, oh yes not born lol

[@invisiblesage7578]

You explain the topics so good
Waiting for your further videos !

[@AliyaBurkit]

Thank you for watching! Glad it helps :)

[@TheSandeepypatil]

a wonderful explanation if possible please make the video for the CFD

[@mohiuddinmasud2174]

Thank you

[@tsehayenegash8394]

Nice explanation please upload atmospheric wave

[@AliyaBurkit]

Thanks! I will try as soon as possible

[@Hino_55]

Thank you Ma'am Aliya!

[@AliyaBurkit]

You're welcome!

[@SheriCoco]

This was good. I understand now

[@bunnyviswa682]

nice explanation sista ,expecting more videos in same style of explanation

[@AliyaBurkit]

Thank you, I will

[@muhammadaizat6641]

thanks, i learning something new

[@Ghost-be7vu]

What a wonderful explanation!!

[@nadeemkhouri4054]

Amazing video

[@navneetnandakumar8959]

such simple n sweet videos! :)

[@diegoguatemala1520]

damn, this was very clear! but I have a question, can the same explanation be used to explain any type of viscosity such as oil and water?

[@AliyaBurkit]

Of course! Viscosity is a property of any fluid. But some fluids can't go as fast as air can go, so sometimes it's easier to describe the motion of other fluids. Air is the most complicated

[@diegoguatemala1520]

@@AliyaBurkit great! thank you so much for your help, you are really helping me a lot in my fluid class!

Pretty good explanation of viscosity.Sad to see that it's so underrated

[@thearun0525]

100 time thanks ❤❤❤

[@AliyaBurkit]

Most welcome 😊

[@kekuleonitro]

Aliya, do you have any ideia about how many layers are necessary in order to air get infinity velocity? It is not necessary to be precise, just to have an idea.

[@AliyaBurkit]

There is of course infinitely many layers, since the molecules of air are so small. But the thickness of the boundary layer will be different for different freestream velocities. The higher the freestream velocity, the thicker the boundary layer will be.

[@kekuleonitro]

@@AliyaBurkit Thank you very much.

[@nicolopradella7091]

Thanks for your videos, I just wanted to tell you that your explanations are always very helpful, cheers from Spain!!

[@kekuleonitro]

@@nicolopradella7091 Indeed!I totally agree with you.

Welcome!

[@udayandas8535]

1:49 100,000 times more viscous than air

[@MR-uk7iy]

comedy always a winner to break the tension

[@wantedgamer1972]

Nice presentation. But your editing is not like that. Because is difficult to understand.but your explanation is good 8/10thank you.

[@khajrymariam718]

Ma'am, what are the fundamental equations of motion describing the fluid flow? I am new to this topic.

[@Tech2Galaxy]

you are sooo GOOD...❤❤

[@muhammadfaizanahmedkhan6371]

Air is 100,000 times less viscous than honey.

[@AliyaBurkit]

Exactly!

[@RAJUBHAI-ww7em]

Tq

[@LM_25_11]

So V Infinity means velocity at the infinity not infinate velocity ,I am not familiar with aerodynamic terminologies so it confuses me

[@EvanWeaver-v9g]

The statement at @5:59 is the opposite of what is true. Completely wrong! When the flow has lower velocities, this is viscous flow. Low Reynolds number = Viscous flow. When flow has high velocity, like the example of Mach 1+ speeds, then you can begin to assume inviscid flow. High Reynolds number = inviscid flow.

[@12deda98]

what film is this? the clip you put right at the start?

[@AliyaBurkit]

Van Helsing (2004) :p

I don't understand 😅

[@Ufuk100]

Ne anlatıyorsun ablacım sen ?

[@Arthanzar]

If conservation of momentum is rho.del.ui/del.t + rho.uj.del.ui/del.xj = rho.f - del.p/del.xi; in the convective (advective if you like) term, why is the first u term uj, not ui?
