@@ChargedTTq Vortex Generators are meant to keep the air that passes through your car attached to the boundary layer. Without them, at certain high speeds your air starts to disperse at the top of the car right before the roof slopes down. In a way they can reduce drag, but not a whole lot cause you still need other parts to help reduce drag.
@@dandingerat exactly, I really dont understand why people like this simon call him idiot yeah it is not some aerospace level of explaination but 99,9% wouldnt get it really or wouldmt care enough to watch
Some people are sometimes unreasonably difficult to please. You’re getting a Mercedes F1 engineer explain things to you FOR FREE and you still find things to complain about. Unbelievable
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 TH-cam 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.
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.
This was very good! You mentions a whole slew of vortex generator types, it would great to have a video going over all those types and show them and pros and cons, performance etc. 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.
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.
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!

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
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
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!
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.
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!
@@bungcheese5901 hopefully no audio engineers and sound designers are watching this. That being said the video is very informative but the echo takes away from the quality
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
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.
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
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.
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.
On your wing, on airplane wings, and on the F1 car photos at 7:09 in your video the vanes are fairly far ahead of the region that creates the adverse pressure gradient (APG). On your wing and on airplane wings the vanes are near the front edge of the wing. I assume that is to give enough room for the boundary layer mixing to occur before the air gets to the APG. On the Mitsubishi and on most cars with aftermarket vortex generators, they tend to put them immediately in front of the area of where the body suddenly slopes down creating an APG. I've always wondered how effective they could be when placed so far back. Thoughts?
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.
there's a reason why the art of port flowing is called "the black art", there are many more variables affecting the gas flow, even good CFD software can struggle to accurately depict what happens in a port, head, and combustion chamber...
Nice you put in the remark about , keeping the marketing department happy 'cos so many things in a mass manufactured item comes down to the engineers being hijacked to keep the business model happy .
If you want to visualize the concepts turn on the pool filter in an in ground pool after dark, lights off, flashlight in hand, look at the shadows the water vortices make, note the compound impact the direction if flow as it navigates the low to high shape of grade of the pool, point the nozzles in various directions watch how the swirls react
I have a question about their use. In amateur rocketry, the fin tube design is pretty tough to attempt to reach mach speeds, since the size of the boundary layer inside the tube increases with speed, until it becomes a total drag (pun intended.) Is there a type of vortex generator that would allow the high pressure to continue to move through the tube at Mach speed and above?
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?).
this comment is before I watch the video. so, I think I understand what they are and what they do. they are a device which create vortecees which energizes the flow and forces it to more closely follow a surface without detatching and creating a wake. let's see after the video if I was right, wrong or somewhere in between Edit: I think I was right, I just didn't have the full knowledge behind it. good video even tho it is old and the audio is pretty bad
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.
Well done. Was reading an article in the LA Times about Jet Blue retrofitting its A320's with vortex generators to reduce noise as the planes descend into the Long Beach airport. Begged the question "what is a vortex generator?" Your video provided the answer. But does beg another question..."are there any potential adverse outcomes to installing vortex generators on aircraft wings"?
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.
Ryan Gosling makes a really good point here. I'm going to install some vortex generators on my wagon , I've been hitting some very high speeds lately ,. my grandmother died in a very horrible way after being run over by a wagon, I think this could have been avoided if the wagon had vortex generators installed .
In simple terms; vortex gens are to suck the pressure aka reducing the high flow pressure and lower it to closer to boundary layer level. So it is a controlled mixing device.
Hi Kyle, could you do a video on the usage of vortex generators for flow stabilization on trailers? I am designing a very light camper trailer (to be towed behind a sedan). In order to minimize potential for dangerous sway oscillations from aerodynamic buffeting, I have already minimized the frontal area and rounded the edges and corners. However, strong, pulsating side winds still scare me. I am wondering if strategic placement of VG's can alleviate these drag effects and make the trailer tow more calmly. My tongue loadings and Cg are nearly perfect, and I have both electronic and mechanical anti-sway; I am trying for reducing the condition which induces sway in the first place.
I recently installed a GT wing on the rear of my Nissan 350Z. You're videos have helped me understand how high to mount the wing. Now my problem is how to know at what angle the wing should be. Could you talk some on how to find the correct or best angle to set my wing.
Kyle, Great tutorial video's please don't take the negative comments seriously. 99% of the negative commenters have no education, very low income and are unhappy people. please keep it up! Thanks

Of course vortex generators generate additional parasite drag. However, if designed properly they can reduce form drag.
If you want to visualize the concepts turn on the pool filter in an in ground pool after dark, lights off, flashlight in hand, look at the shadows the water vortices make, note the compound impact the direction if flow as it navigates the low to high shape of grade of the pool, point the nozzles in various directions watch how the swirls react

Kyle really out here proving his credentials serving up blade runner looks we don't deserve him
Can I hate your separation bubble at 2:05 which is going the wrong way...?
Andrew Rabbitt I noticed that too. Adverse pressure gradient definition is also incorrect.
Can I hate that VTEC YO seems to be written on an evo? XD
Yeah exactly. If he really understand, he shouldnt do it this way!
Ryan, can u explain about vortex generators used in hydrofoil s
Hi Kyle, could you do a video on the usage of vortex generators for flow stabilization on trailers? I am designing a very light camper trailer (to be towed behind a sedan). In order to minimize potential for dangerous sway oscillations from aerodynamic buffeting, I have already minimized the frontal area and rounded the edges and corners. However, strong, pulsating side winds still scare me. I am wondering if strategic placement of VG's can alleviate these drag effects and make the trailer tow more calmly. My tongue loadings and Cg are nearly perfect, and I have both electronic and mechanical anti-sway; I am trying for reducing the condition which induces sway in the first place.
I recently installed a GT wing on the rear of my Nissan 350Z. You're videos have helped me understand how high to mount the wing. Now my problem is how to know at what angle the wing should be. Could you talk some on how to find the correct or best angle to set my wing.
Thanks for the great lesson.. i just can recommend you to put some echo and reverb dampening material into the room to improve acoustics.
Kyle, Great tutorial video's please don't take the negative comments seriously. 99% of the negative commenters have no education, very low income and are unhappy people.
please keep it up! Thanks
