hey im impressed with your design that this only took 2 weeks its really high quality so im just curious on what the code looks like for this design it would be much appreciated if you could share it thank you

man im in cc about to transfer just starting to do projects like this ;(

What thickness is the wood?

i’m in my senior yr looking for aerospace final projects. sos. this is beautiful; i could only wish 😢 great job man

I’m just jealous of the floor cushion 😂 4:11

You not getting the theoretical results might be due to the not matching Reynolds number. In any case that's a great project, thanks for sharing !

I and another college student are currently building one for a school project. We are using the Bell-Mehta 5th degree polynomial as well for our inlet, but are having trouble finding materials to fit the curve we want. What materials did you use to ensure it was accurate?

Hello! I am also in high school and my friend and I are planning one out. My question is how would you construct the contraction cone part with the curve going on two axes going narrower and curving in? Thank you for looking this over.

Can I get the code for the Arduino??

you could try putting a humidifier module at the end of the funnel along with some leds to be able to see the wind, otherwise great vid :)

To anyone looking for more documentation, have a look at my instructables page: www.instructables.com/Subsonic-Wind-Tunnel/ . Otherwise, contact me at jamespkwadhwani@gmail.com. Thanks for watching!

is it too much you ask of you for contact info so i could get a list of materials?? This is very interesting and me and my best friend just out of high school as well are trying to build our own

Nice job!

Hey James, could you share some details on how you constructed the load arm? and is there an off the shelf sensor you used to input the data into the microcontroller?

Thanks- I wanted to build a wind tunnel for flow visualisation. Any tips for making a smaller one?

Thanks for the explanation of some of the details 👏 and for the whole video 👍

Quite impressive you built this in only two weeks. What about adding advanced visualization techniques like pressure sensitive paint, IR thermography, and shadowgraph? Might not show much but create pretty pictures to impress people. Seems the tunnel overall fairly quiet, does it add much heat to the room after long duration of running?

Highschool proyect, I've would do this for college, great work!

Good day bro, is there any CAD files that you can give us for more information about your wind tunnel.

Hey, what part of the build took the most time?

Hi, do you have any documentation to build this? It would be a great help if you can share. Thanks

Did you publish the coefficients of your 5th degree polynomial?

Hey, thank you for sharing such a great know and your build, we have one wind tunnel at our institute but the equipment is not working in it for data collection, could you just guide me how you used load cells for measuring the lift and other parameters and how you changed angle of attack, I know it's your design you can't share details, if you just guide me or any sources that I should follow for it it'll great and grateful to you. :) ..

This is amazing!

how do you measure the results.

Could you share the arduino code? I'm doing a high-school project with arduino wind tunnel

This video is very useful however im just wondering what you used to let you see the lift and drag

Thanks man, a friend of mine and I are also building a windtunnel for measuring drag and lift on cars. It is also a high school project, but compared to you pretty primitive :P. Thanks for showing us the lift measuring device. That gave us some pretty good inspiration. Keep up the good work man!

This is great! I was wondering if you can explain the circuitry part and how I can get the measurements of lift and drag the way you did. What did you use and how did you put it together. It would really be great help I'm also working on a project and need help as soon as possible. Thanks

he looks like a young version of dwayne johnson (when he still had hair) but with a slightly lighter skintone

Hi, thank you very much for sharing this video. I'm currently working on an extended essay regarding angle of attack and lift. I was wondering if there were any sources/guidelines you followed to build this wind tunnel?

Thank you so much for sharing. I’m making an air tunnel for a class I’m taking right now and this was able to help me figure out something I wasn’t able to before. Great work man keep it up!

Great homemade tunnel! Very impressive!
