Coanda Effect

This is what the internet is for.

what a great demonstration😍
Thank you so much❣

What is that thing in the background?

Thanks. Was reading about the Kings Cross fire in London in 1987 and noted this effect was significant in how the fire progressed so rapidly.

Thank you. Exactly what i was looking for

Isnt that the same thing that causes lift on airplane wings?

Sir salute, finally i found this video

Knowledge

I just had someone dispute the coanda effect's relationship to airfoil lift, stating that coada applies only to jets of air ( like your hair dryer), not to larger air movement. But surely the entrainment principle still applies. True?

Is this effect responsible for the aircraft wings for the buoyancy?

Great video. 👍

Awesome Explanation

Danke Bruder!! Brauche ein Video für Physik Referat

So cool when u see the application of the boring theories 😂

TILTING THE BALL OFF AXIS IS EXPLAINED BY BERNOULLIS EQUATION

B E R N O U L L I

WHEN A FLUID LIKE AIR ENTERS A CONSTRICTION THERE IS AN INCREASE IN VELOCITY AND A DECREASE IN PRESSURE

THAT IS WHY THE PING PONG BALL CAN BE PUT OFF THE VERTICAL AXIS THE ATMOSPHERIC PRESSURE BELOW IT IS KEEPING IT AFLOAT

能看到空氣的感覺很奇妙🙂

Actually that with the wine is not the Coandă effect. It's the surface tension that's doing that.

Is it the same as Bernoulli's Principle?

He describes it so clearly and so simply. But we have to address the wider issue here and that is all these physics and mechanic website and blogs are written in such an overly complicated manner that is off putting. Like now I know the coanda effect I can describe it so easily to even a 10 year old but these websites make it so unnecessarily hard.

I love your videos you explain so well!

Does the Coanda effect really explain the liquid scenario? The explanation for the gas scenario makes sense but those effects are not at play with the liquids example. Surface adhesion would be a better explanation for the wine.

Thank You sir

Thank you sir!!!

How about you get some bitches? Thanks though

日本の高校の理科教師です。発泡スチロール球を使って同じような実験を生徒たちと楽しみました。ピンポン球の実験は、5cmの発泡スチロール球を使うともっと上がって感動的です。

Currently studying for a pilot exam. This demonstration helped a lot; so, thank you! 🙂

Mas claro que esto; imposible!
Gran aporte señor 👏🗿

Can you share your Schlieren setup? Curious about the lighting and lens settings. I am trying to film Schlieren but I only get shadows. I can’t seem to get the subject in focus nor lit up.

Espetáculo.

it's the Koalanda effect in Australia

That's amazing!

So this is how Jet Propulsion was figured out

Is that the correct explanation? Low pressure is caused by the molecules on the surface of the ball moving out of the way with the air flow? So the top air is forced down to follow the curvature?
How about the fact that the air up above is already flowing in itself is a low pressure zone and the air by the ball in fact is high pressure and therefore should get sucked up. Just like when you open your car window the air inside the car and things in the car get sucked out of the car. The molecule thing is wrong. At least to a person who pays attention it has no meaning.

May I give an explanation that actually makes sense and have some logic to it.

Look as the air begin to move over the ball, that air gets impeded by the ball, equivalent to when you pinch a hose, the water shoots further, and so the air that is constrained by the ball moves faster as it is following the path which is the ball's surface.
The part of the airflow that hits the ball has to travel faster along the ball to catch up with the rest of the air above it and there is no other place for that air to follow but the surface of the ball.
This is no different that what happens with the airflow on the wings of airplane. Faster air relative to its neighbor is the lower pressure area. In terms of energy, what happens is potential energy higher pressure is converted into kinetic energy, lower pressure.

So if you pay close attention in this experiment you can actually see that on the right side of the ball where the ball curves down at about 2 o'clock or so the air on the surface of the ball catches straight up with the air above.

Excelent explicat!

L'effet Coanda, un ingenieur roumain de qui on ne parle jamais mais,c'est le papa de touts les avions à reaction d'aujourd'hui, voir de chasse.Né à Boucarest et mort à Boucarest,Roumanie.Henri Coandă.Reinsegnez-vous!!!

SUPER.

That was a cool demonstration of Conanda effect!

Science for dummies.
Sign me up.

You people are doing a great work by presenting the fascinating aspect of science ie practicals to students !!!
Salute from India 🇮🇳🇮🇳🇮🇳

I just pour it directly into my mouth. Science shmience.

Still don't know how to avoid the coanda effect while pouring coffee from one thick wall mug to another. Any ideas?

looks like lechs

I know nothing about physics, but I know the name Coanda. This explanation left me no wiser about either the physics or Coanda - I'm assuming it's Henri Coanda, the Romanian credited with 'inventing' the jet engine. That's all I know about him. So is the Coanda effect what made him famous? What impact did it have on the development of the jet engine? Who cares? An extra minute of explanation would have helped a lot.

VERY NECESSARY ))))) NOW I CAN PAY MY RENT OF THE FLAT

Brilliant demonstration.

It doesn't work with olive oil, there will always be some spillage of some kind. But maybe for other reasons since it's so viscous...

That's an explanation. But not a solution. ☹️

👌👌👌👌

we need square cup right
