Diffusers - Efficient Aerodynamics - Explained

为什么生成的字幕是越南语而不是英语

why all hypercars use to SPLIT the AIRFLOW on the SIDES of the car and not let the airflow go over the car??? 2nd question why do the airflow get inside the front part of the hypercar??

awesome explaination!!!!

Thank you for the great explanation and demonstration :)

Does it apply in both FRONT WHEEL DRIVE & REAR WHEEL DRIVE..
Please advise..

Spoons are a lot cheaper than the carbon fiber rear diffuser, thanks for saving me money!

That top car is my 5th gen camaro. It’s a parachute with an engine.

the demo is top notch

Fantastic example, thankyou very much indeed. Wanted to sharpen up my enderstanding of aerodynamics and this was just brilliant! Subbed!

Wonder if you could help. I am trying to improve cooling efficiency in my engine bay of my classic 72 chevy and want to use science to help. I want to use the high and low pressure areas of the front fenderwells to help draw in cool ambient air and suck out hot engine air, but I don't know where the areas of high and low pressure are in the fenderwells. There are conflicting reports as to where these areas are and was wondering if you shed some light to help me out? I assume the engine bay is under high pressure due to the flow of air through the front of the car, I just need to help that air to then escape. I appreciate your assistance.

Just excellent explained

Based on bernoulli, pressure would increase when velocity decreases. Thats what happens in a diffuser. Much like a venturi tube. But i see it is also explained as a wing where low pressure is created due to the diffuser being shaped like a wing, making it flow faster. These two things are contradicting what a diffuser does. Can someone clarify?

Amazing trick!!! I love that example with the spoon!

while the spoon + water does illustrate the concept of aerodynamic downforce due to air pressure differences and the bernoulli principle, the mechanics of that example using water are not the same as an aerodynamic aid.

the water "pulls" the spoon towards the ground due to the mass of the water that adheres to the spoon and is accelerated away from the ground (by adhereing to the curvature of the spoon) which pushes the spoon to the side. force = mass x acceleration. action -> reaction.

Jeeez. How many times have I seen that water and spoon experiment and only now do I really get it!

Oh man! I'm gonna do this while washing the dishes. Washing my dishes would be more entertaining now than before.

In general on production based race cars, where does the muffler sit in regards to the diffuser? above it? within it so the diffuser goes around it? Great video, thank you!

🙌 thanks! This just saved me a whole bunch of headaches 😂

holy moly.. that water and spoon demo is genious! thanks man

so this flat floor and diffuser effect is more effective rear of the body or all section affected?

Very clear explanation...thank you

This made me thirsty😁😂

the water examples pretty cool, i feel like the effect of cohesion is actually the reason why the water is sticking to the spoon though.

Beautifully executed

Good stuff, great demo!!

You are awesome dude

do you agree if a say most of little sport car with diffuser like civic type R, focus rs, audi rs3, A45amg... have just a diffuser for esthetic goal, and do not provide down force at all? Every time i see a review of this car by a auto magazine, they are always saying regarding the diffuser that its a functional diffuser providing down force, when for me its look far from a real diffuser.

Can you recreate the water spoon effect with air flow? Compressor and blow gun ?

a beautiful narrative

Maybe s fork would replicate strakes on a diffuser

So I should buy a diffuser that looks like a spoon.. got it.

Will that spoon fit on my Honda?

Perfect! Thank you sir.

Ok, that was pretty cool. Even a simple guy like myself can understand that.

Wow the spoon thing is genius

This is arguably the most justified waste of clean water I have ever seen.

How could creating a high pressure region at back of the car can help u to suck the air underneath a car

Don't let this distract you from the fact that Hector is going to be running three Honda Civics with Spoon engines. And on top of that, he just went into Harry's and ordered three T66 turbos with NOS... and a Motec system and exhaust.

DUDE awesome video! You really helped me understand this!

Absolutely great video

if i was to use a small model of a car and race it along a straight track, what anglewould i need on the back of the car

u r beast at cars

What about the holes people have been cutting in bumpers as diffusers, how does this affect the aero at the rear of a car

Diffuser=Upsidedown wing on the back of a car

is it better 2 have curved diffuser rather than a flat one and how do I calculate the angle I need ? thanks Ryan

You are the king.
