Hey everyone, I'm Sean, the designer of the bladeless fan. I want to point out that the supports that everyone is saying should be angled are not solid vertical walls. They're small pegs that attach the concentric domes together. If you look really closely at time 3:30 you can see what I mean. There are basically just dowels attaching between the walls. I tried really hard to have the least amount of surface area pushing air instead of dragging it by the boundary layer effect, and honestly the first thing I would do on a version 2 is remove most of the supports, because the fan is much more rigid than I expected. I know the fan has a lot more improvement to be made, this was just a proof of concept that I spent about an hour on. Also, it definitely is losing some energy to air that drags along the outermost wall, but if you watch the smoke test carefully you can see that some of the air is actually sheeting down along the wall and getting blown through the fan, and this is because of the Coanda effect. Let me know if you'd like to see a bladeless mk. 2!!! I'd love to try and iterate on this design, but I'm not planning on adding blades to the design like many have suggested. It's sort of a self-imposed design constraint to see how well I can take friction and centrifugal forces, two major causes of inefficiency with fans, and use them to make a fan work. The fan may be greatly improved by adding blades, but I would rather push this concept further before compromising and adding blades in.

[@durdaldo]

I think this fan is a great idea. I also think it likely has pretty poor static pressure, I'd be curious to see if it was a good case fan that was exchanging air with little resistance rather than trying to push air through a radiator.

[@fjrapper436]

Dude your amazing please make another one this is almost similar to Nicola Tesla blade less turbine

i'll make a fan that is just a piece to go on the bearing surface and no blades to win the quiet contest

[@FreekHoekstra]

Bladeless is ingenious, using the friction to throw outward, and using the geometry funneling it backways, really really clever, and maybe a very niche market could have real use for this!!! Edit, for those making fun of it as a gimmick, thats a pretty limited view, there might be engineering cases where one has to optimize for safety, or very laminar flow generation, therefore blades may be ill suited to the task, but this would work well. Just because we don’t immediately see a use for something does not relegate it to be a gimmick. Its new, it works differently, and so we need to think about what would benefit from its unique strengths

[@ferrumignis]

It's basically a centrifugal blower with an integrated duct.

[@zlac]

It loses quite a bit of performance because the intake is smaller than its output. We know it's better to blow than suck for cooling, but this one might be better if it was sucking actually! Then you put it on TOP side (not bottom) of a tower cooler inside the "tower case" so it only aids the natural air convection - hot air goes up! Could be real nice actually!

[@sepg5084]

It has poor efficiency on both cooling and sizing. It can be a gimmick product, installed for the lulz.

[@Crown-Fox]

An improvement on the Bladeless would be to curve the vertical supports slightly towards the direction of the spin. I guess it wouldn't technically be "bladeless" anymore, since they would function similar to blades, but it would increase airflow along the outer edge, and pull air in a bit better.

[@milaanpatel4997]

I am glad saw this channel. Just finished watching the entire playlist. From what I understand, is that most of the fan do not blow air in streamline and this has to do with how leading edge is designed. The most difficult part in fan blades is to maintain the optimum angle of attack. The velocity at inlet and RPM of the fan determines the angle of attack. Velocity at inlet is specific to each fan design and is normally tuned based on trial and error using simulation. The RPM of the motor is not a fixed. It is dependent on the fan weight and drag. So it is really hard to estimate the optimum angle of attack. A more simpler fan with large tolerances to inlet conditions works better and more sophisticated blade design (like the turbo jet blades) perform poor, as they need to be tuned to right conditions. Sometimes it's is just luck. Overall , it is very interesting series. I might make one design of my own and send one. Even do few test prints using my Ender-3.

It would be interesting to test the bladeless at higher RPM, with no blades it should take very little power to run it at several thousand RPM.

[@gavinhicks7621]

Any air touching in the middle when the fan is spun up is also getting spun and that spin produces an outwards force pushing the air into the outer curves then out the back

[@802Garage]

Air has mass. What happens when you spin a mass? It wants to go away from the center of spin. When air is displaced, it creates high pressure where it is displaced to and low pressure where it is displaced from. Air always flows from areas of high pressure to areas of low pressure. By pushing air out of the fan through the concentric open dome rings, it creates a low pressure area in front of the fan, which air then flows into and the cycle repeats.

[@fermitupoupon1754]

it isn't technically bladeless. There's radial supports between the concentric rings. The supports work as impeller blades.

[@802Garage]

​@@fermitupoupon1754 Yeah, they essentially just act to compress some air to allow the open dome like shapes to do what they will with it by channeling it over the shape. I'm wondering if adding some angle to the supports would make a big difference.

[@JD_Mortal]

To make a fan "equal", in pressure delivery... You have to twist the blades flatter, the further you get from the center. The easy way to do this is create your inner-angle first, and simply rotate the fan and pull a line outward from the inner angle, to your outer-edge. (In code, you can just project the angle from your inner angle, to the outer-edge, spread-out so the lines all intersect the center of the axle. But your blade will be larger as it expands out. You put MORE twist back into it, if you make the blades more narrow, but you will introduce more noise and completely nullify equality of pressure, creating a "pulse" as that gap between blades expands.) This is because the outside edge of the fan blade is spinning faster than the inner part, near the axle. It travels a greater linear distance, so it needs to be less of an inclination. Otherwise the outer edge of the fan will be "pushing air outward", while the inner part will, relatively, be "pulling air in". Adding a "cone" to the exhaust direction, will also quiet the fan a little too. Otherwise you create a "void" that the air is constantly collapsing into, which creates a faint pulsing, at high speeds. That is why jet-engines have a cone at the exhaust, off the turbines. It has to be designed for the specific air-flow that you expect to be moving. The faster the air-flow, the longer the cone has to be. The slower it is, the shorter and more blunt it can be. (Slower air will diffuse faster and faster air will thrust out before expanding, creating a form of "Venturi effect". That is why a "free-air" fan seems, initially, to be better for massive air flow. Only a fraction of air is being moved "by the blades", the rest is ambient "flow", pulled-in to motion, by the directed air.) A pure quiet fan would be a simple "balanced disk", with stationary "wipers", that skim air off the surface as the disk spins fast. Hard-drives use a form of this air-skimming, to help float the head off the disk, as well as circulate the air internally, within the pressurized case of expensive nitrogen-filled drives. The best "free-air" fan is a simple "propeller" style design. It has the greatest "free-air flow", but low "static-pressure". Actually quite a horrible design to use for cooling, but great for moving a lot of air around, unrestricted. The best fan for moving high volumes "through restricted mediums", like filters and cooling-fins and radiators, is a "squirrel-cage", or "blower fan", which uses lateral blades, arranged in a circle, and harbors the power of "centrifugal force", as well as airfoil properties, to "pump" massive volumes of air, at high pressures, through constricted mediums. Though, it is notably less volume than a "free-air" design, in "free-air"... It pushes MORE, under high static loads, than any "free-air" design can possibly ever do, with less power. (You can get a venturi effect with a blower-fan too, making it more powerful than any free-air fan, which is the secret to the "Dyson bladeless fan" design, which actually has a blade, out of view.) The right tool for the right job... Computers, for years, have used the wrong tools, because they were cheap, or adequate, "out of the box", but not "in regular use".

KZbin is weird! How in the world I never came across your channel! I subbed immediately after this video. Love the content. Thank yous

A video series about Fan Showdown? I'm a fan of it now.

[@Oblithian]

👌 _Fantastic_

I knew the bladeless fan would work. It is basically a very inefficient "inverse" Tesla turbine ("inverse" because it is not a turbine, but a pump). Different medium, different flow (and energy flow) direction, but the same principles.

Fanning the flames of fandom with the fans of fans, that's fantastic.

[@TheNukedNacho]

Man's got a whole series dedicated to testing fans with sound and temp comparisons. Meanwhile, my set up is a gaming laptop on a stand with a desk fan next to it.

To that bladeless fan, if you add more supporting ribs to those concentric rings, it can move the air from rest to rotation faster.. delivering the centrifugal force quicker..

This channel gives so much fun specially watching those smoke being pulled in.

[@Natetherocksmith]

I don't know why these fan videos are so interesting, but it's why I subbed. lol

[@tenoki]

We get it. You vape bro. /s The fan showdown is one of the most unique things that I have seen on YT and I am glad that it is still going strong.

[@ElAnvaBar]

I like his dedication to his fans.

Hello there from Philippines im an aircraft technician only just sharing my thoughts to you.Just make huge fan blades but not to much for the motor and motor that run only low rpm but high torque,this reason you could minimize noise. In your experiment i think you are not looking for compression so you dont need hugh speed motor but just lower rpm with high torque in low rpm. But if your looking for some compression just make simple a CENTRIFUGAL COMPRESSOR or in EXTREME AXIAL COMPRESSOR with many stages of rotor blade and stator bladed

The “blade-less” fan isn’t free from “blades” they aren’t exposed in the traditional sense, but there are still blades and they are just enclosed. The vertical structure walls that run the length of the cone and have a pretty substantial width are in a sense directing the airflow down and to the layers of circular channels while exiting out the concaved slits. It’s just a different design.
