@ALifeOfWine
3 жыл бұрын
It somehow manages to keep the airflow central rather than dispersing it away from the fan. Don't know if that's because of the slits or if it would still do that without them though. I feel like there's finally been a concept that's proven itself to the point that it needs further iterations.
@Thelothuo
3 жыл бұрын
man i wish i'd been keeping up with this series earlier The SWAG's slits to let a small amount of air through to the upper side of the airfoil are not just aesthetic, but necessary in its design. In aircraft, these intentional leaks are used to prevent stalling when the plane's angle of attack is too great, which drastically reduces lift while drastically increasing drag. In this fan, introducing these leaks allows for a far more aggressive blade angle without stalling, which would drastically decrease flow rate and speed. From the side shot of the SWAG at 3:40, it has quite an extreme blade angle indeed! Keeping the flow central is mostly something else though. Because fans rotate, air passing through them gets thrown away from the center as it is pushed through the fan due to centrifugal acceleration. Simply put, the air touching the fan gets swung away from the middle. This effect is generally not desired since air moving away from the center means energy is being wasted on accelerating air away from the center and since it means less airflow at whatever the fan is pointing at. Fans usually compensate for this by giving each blade a reverse sweep, such that the curve of the blade as viewed head-on scoops air back toward the center like a scythe. Even the SWAG has a small sweep like this. The slits however _may_ also help a little bit by interrupting this axial flow away from the center, creating a trap on the bottom side that air falls into and a wall of leaking air on top that blocks air from crossing the slit.

The ptoblem with the mono is that it isn't dynamically ballanced. If you have a stick with a small weight far out on the left side and a bigger weight on the right side near the center, it will be ballanced when still. But when you spin it, the small weight moves a lot faster and the balance moves to the left side. Static ballancing is better than none, but dynamic is the only way you can achieve a perfect balance.

One reason people have so much trouble with a monoblade is they need to take into account the force the blade is exerting on the air and the greater friction the blade side has with the air. I might suggest adding tiny horizontal fins that would create drag equivalent to the fan blade It doesn't matter how perfect the center of mass is if there is a significant force acting unevenly on the fan.

The idea behind the vents in the blades is to reduce vortices which would reduce airfoil efficiency but that is typically for low air speed over the wings or high angle of attack.

I knew the swag was going to perform great, those gaps in the airfoil are similar to the gaps in bird feathers and they actually help to reduce vortexes coming off the back of the wing or something.

One thing I noticed thanks to the side view that the numbers don't tell you is just how much the WID dispersed the smoke over a wider area than the others. I feel like if you put that fan in the top of the case with other more normal style fans in the other positions, it would bathe the system with a wider swath of fresh air from the top down, while the other fans bring in a more intense but compacted air flow. The two types in unison could possibly improve the overall temps of the entire system... VRM's, RAM, etc...

Love the side view! I feel like it gives a new perspective towards the “air flow efficiency”!

That progressive airfoil really helped deliver more static pressure I bet. It looked really efficient in the smoke test. That side view made it immediately apparent which fans were spending most of their energy pushing air straight out the back of the fan, and how many were wasting most of their energy spinning the air around so it flies out to the side as soon as the fan isn't containing it. I'm betting low helicity and high velocity equates to better performance in a radiator cooling test since the air encounters the least resistance travelling in a straight line perpendicular to the radiator, so the more the fan is making air move that way, the better it will do.

Those fan blade gaps on the third one you showed create low pressure zones which could very well draw even more air in than without. That is at least the working theory I have based on fluid dynamics.

so late in 2020/21 i started trying to find weather ANY disposals had the scary blades like people think and was designing.............. some of those same basic shapes that's pretty cool like kiki's fan just really grotesque and gnarly/sharp with tons of spikes and edges i love that fan you might say i'm a _fan_

Ah, for those one-bladed designs I wish you'd test the print's centre of gravity and just slightly file down one side to make it even. Great show nonetheless!

Even if the fan doesn't blow in the center, that's not why the smoke goes there. When you have a circular cross section of airflow, or like a pipe, the highest velocity will always be in the center during steady state flow, because the outer edges create drag from the still moving air or pipe walls.

Man the show as come such a long way! Great fans this round! Loved this!

I’d really love a static image of the fan during each smoke test, sometimes hard to distinguish, and the names are always Wild lmao.

0:45 oh i get it, looks like the counterweights of a crankshaft. bonus points for creativity.

Where can I find the STL files for these fans so I can use it my self?

I'm getting young Anakin Pod Racing vibes with seeing Sssata's fan in the smoke test. "It's working! IT'S WORKING!"
