Since UKposts is about to delete annotations, figured I'd post them here for everyone to see. Enjoy the video! 1:59 Whoops, this is meant to be an increase in pressure, not a decrease in pressure, my bad. Click on the card for more detail on the adverse pressure gradient.

Thanks for the lesson Ryan Gosling!

as every genius engineer must, you draw terribly. awesome explanation

I really appreciate the credentials. It's nice to finally see someone on youtube who actually knows their $hit. +1

My favorite part of the video was when you set everyone on fire by proving you have you paper in this field.

I've used this video as a supplemental explanation for my students in aerospace physics. Great job!

mildly informative? bro free engineering classes 🙌 bless your soul haha. I was at ASU studying mechanical engineering joined, FSA too but couldn't wait to build my own stuff. Hence I'm attending a top notch fabricating school. your videos are immensely helpful. I hope to get my fabricating UKposts page going soon 👍 video editing in process.

When you brought up the example of what they thought when designing the EVO´s aerodynamics I understood exactly how it would play out. It basically helps the wing to do it´s job more properly to push down the rear end for down force.

Excellent, Kyle! I appreciate your diligence and hard work bringing aerospace to the masses

This video was quite helpful to me! It made it a lot easier for me to understand what vortex generators do and how they improve the airflow. Looking at this from an aviation perspective (specifically improving the stall characteristics of wings) this was an incredibly helpful video explaining how that works. I was previously confused as to how disturbing the airflow over the wing could work to improve the stall characteristics, but now it all makes sense! Thank you very much for your highly informative video!

Outstanding videos. I'm an aero mech engineer myself, and have a huge passion towards aerodynamics. These vids are like crack to me. Keep 'em coming!

This was very helpful and informative! Thank you for taking the time to explain them!!

Nice work man! U alongside with Engineering Explained make a perfect duo for enlightening us and making our automotive knowledge expand to respectable degree. Thanks

I so love getting knowledge from someone who actually has some. Thanks for sharing.

Great presentation. As an aviator instructor, it helped me to understand and provide an excellent example for explanation.

Thanxx bro.. finallyyy got it. Have been trying to understand VG , after watching a lot of videos, yours made complete sense. Thanks

Sir, you just efficiently described the major parts of my aerodynamics course. Bravo

Would love to see examples of the different types of vortex generators you mentioned in a future video. Thanks for these, nice work!

Why would somebody say you don’t know what your talking about? I have an aeronautical science degree and I enjoyed the refresher. Thank you! Great video!

You have no idea how much your video helps me with my term paper. Thanks,

I have an interest in aerodynamics, esp. for cars, so these videos are very crucial. Thank you for making these.

Thanks, Will look to your trainings before the aero stages on the Jag.🏁 Best to you Scott Whitmire

New subscriber, love this. Informative, interesting and best of all. It's understandable. I will never look on a race car the same again.

I had no idea there was such a thing. I learned something completely new and your explanation was clear and concise. Subscribed!

really good video. you did not have lots of materials in the video but still the explanations were very much clear enough.

Did he just predicted that Civic type R will have the vortex generator

I'm Currently studying to become a aviation maintenance engineer... i had a hard time understanding exactly how vortex generators suck high energy air into the boundary layer... You said the exact same thing my instructor said in his explanation, but just seeing you use a diagram while you explained gave me an epiphany... thank you

Love what you do, man. As a supportive comment, I'd like to mention there is a science or two on being able to hold the attention of the viewer/listener. I'm talking about audio quality. The ghastly echo in your voice recording which you created by relying on the built in mic of your camera...several feet away, can be easily solved by clipping a small mic to your lapel. You could also use a boom mic just out of your shot, but since you move around a lot, you"d need an operator. In other words, to hold the attention of even seriously interested, technically minded viewers, you need a mic close to your mouth. This will help you present your world class information in a world class manner. Once again, love the great contribution to racing education that you make.

Wow this video is amazing. I'm writing a paper on Vortex generators for my minor project and this surely helps!!

That was explained exceptionally well. Thank you!

Just discovered your videos, love them bro!

Best one yet. Love the beginning, chopping up the haters :). Great stuff Kyle. Keep on sharing the knowledge please. Regards JW

Man I'm in love with your videos, keep it up

good video very informative, if i could make a suggestion it would to reduce the echo from the room when filming.

Old vids are still informative. Wish I was an aerospace engineer majoring in race car dynamics. I'm just a home hack with no money trying to build race cars in my spare time.

Thanks for the explanation ! Appreciate your work

Great videos - Would love something that goes a bit more in depth on what types of vortex generators the average person might DIY in their garage for a budget limited race car.

I really wish more people who think they are gear heads were informed like you are. I have watched videos of people going down the road with there coors beer in there buddys truck calling out every car with any aerodynamic mod on screaming that they are a racer. I would have not know what a Swan Neck Wing was if it was not for your video. You make perfect sense when you explain. keep up the good work

You got a subscriber and a like from me. Thank you and please keep it up, this has been informative and it made complete sense. The reason I watched the video is because I am trying to improve my car for autocross and I wanted to learn about vortex generators. This was exactly what I needed. The only question I have left to answer is do they make more of an impact at higher speeds, my inclination is to say yes as it is probably easier to measure the impact they make at higher speeds vs lower speeds, but the effect they have is present regardless of speed, therefore I think it is wise to install these if your goal is to improve track times. Also I like the bit where you explain the "flaw" behind the evo designed vortex generators, as they are not the most efficient vortex generators, so I should do some research and find vortex generators that actually work before making a purchase. If you have a recommendation on a manufacturer of aftermarket vortex generators that would be superb (or you could always make them yourself, as I am sure you could make a competing product. Also wouldn't you think it help improve track times if vortex generators were installed at every angle?).

When I was a Truck Driver we put Vortex Generator on the aft edge of the cabs and Trailers and the difference that made to stabilizing the vehicles was very impressive, and the unexpected fuel saving was a surprise but very welcomed.

aerodynamics tips for better fuel economy please. that would be a great topic that everyone could apply.

This has helped me alot in regards to understanding this phenomoinon.

Nice video, good explanation for low velocity air flow. High velocity appears to react very differently, flow separation always occurs.

love your work. im a new subscriber and absolutely love what you do. you remind me of Engineering Explained, but you go more in depth in real world workings rather than just concepts.

Took me a while to find you. Like your videos. iRacer here PCA coach, so working with aero is new to me. Running a Merc AMG GT3 car. Thank you- it has got me thinking. --S

Cheers mate, Very helpful and good and the Explanation along with applying the Scientific Proof of what Vortex Generaters do. 💯

Nicely done!

Thanks for the information Kyle. It led to me do a lot more research to understand how they work. I realized that a vortex generator is useless on my car and possibly counterproductive.

Hi, I watched your entire video. I don't know anything about this science but found your explanation interesting. Good video.

Trust me , i know what im talking about 😂 i love this guy already

Pro tip for acoustics, grap some towels or blankets and place them on the floor or around you to dampen some of the eco. Also, good video :)

Thank you, it was very illustrative.

that was an incredible explanation

Very helpful video. I am interested in the aeronautical application for VGs and your video explained it nicely. Be it a car or airplane wing the same principal applies, just you car guys want the lift downwards and we airplane guys want it the other way. Thanks for a neat video.

This is awsome!! Great job

Sir you got a subscription very informative thanks and keep up the good work

Very interesting ! Thanks for the explanations

Love the trenchcoat, good info too. Thanks.

That was absolutely brilliant... Spot on =)

Lool that flex in the intro 💪🏾 tells me i came to the right channel 👍🏽

Thank you for sharing great work 👍🏿

Great video! Highly informative.

Damn I hate the room where you are speaking... that sound tho...

Thanks very much for this video. In between people like yourself, and being given a copy of 'Race Car Engineering by Paul Van Valkenburg' when I was 8, I feel more confident in making aero changes to my race car, because I feel like I might have half an idea what I'm doing now, as a privately funded person without oodles of cash or a wind tunnel.

There are many different kinds of vortex generators, such as simple plow, shielded plow, triangular plow, scoop, twist interchanger, ramp, tapered fin, dome, shielded sink, wedge, vane, wing, fences, leading edge fairing, dorsal fin, etc.

I see vortex generators on airplanes that need increased short take-off performance also. Thanks for the informative vid. Now i have a better understanding of how those devices work.

Great explanation!

thank you very very much for your time and your explanation

Nice info. I had no idea! Thanks!

Great video, I've subscribed and am going to watch your other videos. Thank you!

Great explanation ! Thank you !

Would it be too much to ask for you to make a video going over the different types of vortex generators like you did on the diffusers?

Thank you Kyle 🏁🙏🏼👌🏼

Thanks for the great lesson.. i just can recommend you to put some echo and reverb dampening material into the room to improve acoustics.

Most enlightening, great stuff ... I like seeing cars with VGs and no spoiler. Hehehe ...

love the test rig!

super informative ..nice vid bud

You got my like on the intro, i cannot wait to hear more :)_

Best aero explanation out there! I'm looking to implement this tech for wing sails, endplated, Sail GP style. They use a double slot wing with a essentially a huge adjustable flap at huge angles. Ive never seen vortex gens on them. As you say, every little helps!

Thanks for keeping it real. REALLY real !

Thanks for the explanation.

Left handed drawing is difficult. I'm left handed so don't sweat it. Clear concise explanation. I'm currently re-engineering my 2017 truck for better gas mileage through engine calibration and I now realize that aero needs to be part of the solution. Underbelly as well as the roof to the rear wing need smoothing in order to cut down the CD of the vehicle to make more progress. 20% savings isn't enough for me.

Kyle, very well explained. Could you perhaps make a video to explain this concept on another application, be the edge of a bicycle tire. Mavic came out with the CXR and CX01 blade that smoothens the surface area where the tire mounts the rim, yet insisted on using their tire which has tiny ridges to create a gradient vortex at the leading frontal edge of the tire. In trying to understand their design and science I came accros this video. I would be curious to better understand where tp make this vortex on the edgw to have the greatest effect

Excellent Lecture. A+. Thank You.

You really do need A LOT more subscribers. So in-depth stuff compared to any car related videos on youtube.

This is a trip back for someone who just started watching your stuff recently. (I like the beard, fyi)

I 'd love a tutorial on airflow of engine ports on heads, both intake as well as exhaust. you certainly know your stuff!

Love your work

Such a good lesson, thank you.

Love the content. I used to have a Very-EZ airplane that had a canard wing.

Great explanation! helped a lot, thanks! :)

I will add to what Kyle is saying here - I drive a first generation Dodge Stealth with the so called "banana" spoiler which is at the base of the rear window. I tuft tested it and wound up with swirling blah airflow over the top of it. The tufts went in circles. After I added the vortex generators, the airflow is now nice and straight, top and bottom.

Hi Kyle, Great You Tube Channel, it is very informative. It is nice to find knowledge freely shared. Keep it up mate. I have a couple of questions on VGs and drag reduction on my 4wd wagon tow vehicle and caravan combination. I am planning on making the mods myself and hope to reduce fuel consumption and increase stability. I have found quite a bit of info but a lot of the detail is kept secret for sales purposes I guess. Anyway, I have three main ideas. Please consider them and let me know what you think. 1. the most obvious mod is a deflector foil placed near the rear of the roof of the tow vehicle. I will guess the angle to be about 40deg and 500mm long. I was thinking of using long threads to view the air flow in real life. The idea would be to have the air flow join with the flow over the van roof. Would VGs on the deflector make any difference to how far the flow goes before dissipating? 2. I have read that VGs placed along the rear edges of the van will assist with reducing drag on the rear of the van. Do you think that is a valid idea? I cannot decide if it is good or bull so I need a wind tunnel to test theory. If it is valid what type of VGs would you use and what spacing? 3. Failing the VGs on rear edges I thought about using a partial boat tail, angled at 10 deg and about 750mm extended. Your thoughts would be most appreciated. best regards and keep up the excellent channel, cheers n beers, Mick

Loved the video, definitely subscribing!! I am currently studying and you love to read some of your papers, where could I find them? Cheers Kyle

Thx alot for explain and presentations

Never knew Ryan Gosling is a aerodynamic expert. Great video btw!

F**k the haters, keep the information flowing!!! (no pun intended)

Dude your videos are awesome!!

Watched this video of yours again Kyle just after watching a young person installing “vortex generators” on his car. Thought to myself, someone once correctly explained vortex generators before and this young person hasn’t got it quite right. This young person certainly didn’t watch your video Kyle, poor show! :-) Then right at the beginning of your video you show the exact same mistake as I’d just seen. Yes I did have a chuckle. So glad someone knows what they are talking about. I’m trying to decide where to install vortex generators on a model sailplane that suffers with scary tip stall at slow speeds. Would you suggest vortex generators in front of the ailerons or at the 40% chord? Great, well presented video Kyle. Great style and not afraid to put people right. Very good. More thumbs up for your video Kyle.

Lol love how you flexed your knowledge on us in the beginning of the video 😂
