Can vortex generators be used without a wing to reduce drag? On the rear roof of the car or even the decklid?

@faithstormer1976

@@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.

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

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.

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!

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

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

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

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

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!

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.

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.

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

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

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

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

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.

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.

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

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.

That was explained exceptionally well. Thank you!

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

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

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!

Just discovered your videos, love them bro!

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.

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.

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.

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

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

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

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

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.

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

Great video! Highly informative.

Thanks for the explanation ! Appreciate your work

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

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 :)

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...

Thank you, it was very illustrative.

Can you do a video on vortex generator profiles and what different profiles can be used for? Awesome channel btw. Really good info.

Ive been watching a bunch of your videos starting with the tires and how they perform, and I must say your explanation and knowledge is quite impressive and I have learned quite a bit today. That being said, this video has got me thinking about the vortex generators themselves, how exactly to they create the vortex in the first place? I understand the purpose of them but I cant really get HOW they make the vortex. Do they change the velocity or pressure of the airflow at a certain point?

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

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"?

Excellent Lecture. A+. Thank You.

Nicely done!

Hey Kyle, that was very Informative,thanks. Wanted to more about how they design deep space shuttles, satellites considering if the dense space shock waves with abrupt pressure gradients come into the the picture and the shuttle being in no aerodynamic orientation?

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.

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.

thank you very very much for your time and your explanation

This is awsome!! Great job

Great explanation ! Thank you !

Thank you for sharing great work 👍🏿

Good as far as it goes, the direction of rotation of vortices, how each different rotation is created and their effect would be a very useful addition. EG if a vertical triangular generator has it's front angled to the right in which direction will the vortice rotate looking from say the front?

Great explanation! helped a lot, thanks! :)

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.

Thank you so much, that helped me a lot. I'll be having my exams on this coming week. I'm an aircraft maintenance engineer.

Great explanation!

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

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.

Thank you Kyle 🏁🙏🏼👌🏼

that was an incredible explanation

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

Thank you for the informative video! Would adding some vortex generator on a street car have any benefit at all? I am thinking about a bit reduced fuel usage on a highway around 130-160 km/h. What about downforce? Would a laminar flow over the vehicle increase the downforce a bit? I have a 6 gen Civic VTi, and I wouldn't mind a bit lower fuel consumption on the highway for "free". Also it would reduce the noise a bit I guess (less drag>less power required for same speed>maybe not that loud). I love the sound of the car on a mountain road, but for a 2 hour drive it's not that pleasant.

Fantastic tute! thank you. Can you tell us if adding vortex generators to the windscreen edge of convertible will help stopping air entering the open top, and turbulence? any thanks
