- I made a small wind tunnel out of 2 computer fans and a few other custom parts and electronics. The wind tunnel is currently capable of creating streamlines for qualitative analysis. I plan on adding a pair of small load cells to measure the aerodynamic lift and drag forces acting on the test piece to gather quantitative data. Stay tuned for future projects!

You should maybe consider a closed design that pulls the air to the back. If you make it so that the only intake is your pink grid you can get the air to be way more laminar.
I was thinking the same thing. Close the side and top, keep the grid at the front but move the fan(s) to the rear of the tunnel. This will allow for less turbulence at the grid because the smoke will be pulled instead of pushed.
What’s the scale speed of the wind?
I love the way you made smoke, what a great idea!
This video was really cool! Keep up the good work 👌
This is really AWESOME!!!
Have you thought about making long exposure photographs? I think you could achieve a more 'precise' visualization of the airflow as a mean.
4:00 That is why you must put the fans on the back sid for suction. The fun create a lot of turbulance on the exit.
The wire and oil is nice idea but look to costly and hard to deal with eat when working on project.
And vertical mode will be better for analisis. In horizontals you cant see the lamination and where drag start happen.
Amazing its simple yet effective i will deffinetly use this for my physics project cheers!
Did you do this test with a load cell?
this looks great
tryna do this for science fair, what can you use to run a current through the nichrome wire, and will any amount of current work?
you can find charts of expected temp vs wire gauge and current. I recommend getting a cheap adjustable DC power supply
This is AMAZING!! I love wind tunnels and have been working on one. I really like the contraction cone, much more optimal that the more rectangular ones you see more. I 3D printed the air laminator too on my new one, and it's so much easier than cutting hundred of drinking straws XD
Hey man im wondering how you connect the nickel chromium wire to the battery, im thinking about doing this as a science fair project. Can you post a video on what it looks like from the back and how you connected everything. idk if u even still have it but if u do mind showing what it looks like from the back. Anyways a great video and a great idea as it solved a whole bunch of questions i was looking for!
I would use aligator clips
@@BenjijartIm wondering if their is any other wire i can use instead of the Nickle chromium one? Thanks a lot i appreciate it.
@@younesbahiani steel might work. Nichrome is easy to get on amazon though and is intended for use as a heating element with documentation on temperature vs current vs diameter etc.
@@Benjijart Hey is it possible to use a 9v battery to heat up the wire, maybe 2 or 3 of them lined up? I'm not trying to go out and spend a lot on a power supply or something too expensive and I'm wondering if theirs an alternate way to heat it up.
@@younesbahiani probably yes but they have less power output so you may have to use really thin wire. there are tables online that equate current to temperature for different gauges of nichrome wire. You should also be able to find ohm/m for a given gauge of wire. Use ohms law and don’t forget the internal resistance of the battery in your calculations
You are so underrated!
hey, i tried connecting my nichrome wire to new batteries (4,5 and 9V respectively) but they don't heat up. When connected to the wire the voltage of the battery is measured to be 0,3V. what are the exact voltages and current of the battery you use for your wire?
I used a 2S lipo battery. Internal resistance of alkaline batteries might be too high which could explain why the terminal voltage drops like that if thats what youre using. If you connect many 9V alkaline batteries in parallel it might be enough.
Hey, I've piked your old videos a lot, qnd wanted to ask, if you could maybe someday make a tutorial for a german M1915 Gummischutmaske Gas mask?
did you just apply the glycerin using a paintbrush only? would there be any better way to keep it on for a long time?
You could probably make a dispenser system with a peristaltic pump and some kind of manifold to automatically drip onto the heat wire. Or gravity-fed like a funnel that leads to drip-nozzles or something idk.
Yo. Why did you delete your gamepad videos? They were soo good but if you explain i will get why you deleted them(or privated)
how is the smoke actually generated?
NiChrome heater wire with glycerin that gets vaporized
could you make another ww1 gas mask? cool video!
@Benjijart , I want to make a arduino uno controller, i have i error, i described it in that video coment. Please help me with the problem.
good video
Hi.
I loves your creativity please reply me I have a question
Awesome sir❤️🤩🤩
What are the materials
so cool same as mil $ wind tunnel
Hi.
I know this isn't related to the video, but I need to ask you something.
I made an upgraded version of your accesibility mouse controller for a school project (I just added a few buttons, made them bigger and easier to press and it just feels better that way in my opinion).
And I was thinking about patenting it and selling it.
I know it isn't exactly the same product as what you did, so I don't think I need your permission. But I feel like it is the right thing to do, since your video gave me the idea.
I hope you see this, if you don't I will probably comment the same in your next video (sorry if that bothers you, it's just very important to me).
I hope you the best, you make great projects and videos.
See ya.
I think that's fine. As long as your controller does not use my 3D printed component which i designed and is under a creative commons, non-comercial licence. Furthermore, you will have to check with the author of the arduino library since the entirity of the code is his design but it looks like his licence is commercial.
@@Benjijart Thanks man. My 3d model is 100% from scratch so don't worry about that.
If you do sell this, where can I get one? My brother and I are planning on making a custom f1 car, but before we do we want to 3d print a small one to see its aerodynamics and how it performs.
Pog
Put an hotwheels on it and see what happens
