What a nice and informative finding is your channel. I my self had the oportunity to adquire a french missile wind tunnel model some years ago and I look forward to learn about its functionality with your helping channel. Thanks so much.
Brilliant video I will be starting my role as wind tunnel engineer next year and I cannot wait. This has given me a little insite on how we measure different aero dynamics. Thank you.
Thanks a lot Tom, I'm glad you liked it! Feel free to connect on Linkedin as well (Wouter Remmerie) to stay in touch once you move to the wind tunnel. Best of luck!
Fantastic series Wouter. Quantifing pressure is a hot topic amongst competitive speed skydivers & wingsuiters. Thanks for putting out this high quality content
Thanks a lot Meirbhin! We've been discussing simulations a lot with other speed sky diving professionals. Wouldn't feel good to drill holes in the body, but there should be alternatives to measure the surface pressure on the body 🙂 we do sims on 3D scans of athletes to analyze and optimize their equipment and position. See this video: th-cam.com/video/DqlDpUFcScc/w-d-xo.html
@@AirShaper I've been following your work with cyclists and skiers. Very interesting indeed. Unfortunately I sustained an injury which impacted my plans on a mesh scan this year, but I did commit to drilling holes in the body haha
@@MeirbhinOConaill LOL :D I hope they didn't have to put too much metal inside your body to recover from the injury. For athletes, our customers sometimes work with "parametric" 3D models which can then be fitted to measurements on the real person. Less accurate but perhaps more accessible.
I wanted to build my own wind tunnel in high school .. I got the air flowing through it quite nicely but then I started to think how to actually do some quantifiable observations and this is where my project fell apart. Looking back, I should have limited myself to some simple smoke and a high speed camera ...
Hi Jure, in a previous job we did the same and indeed, the measuring equipment cost almost as much as the tunnel itself! Force balances aren't cheap 🙂 perhaps the cost ratio changes for larger tunnels
The streamlines indicate a specific path for the particles released at the smoke outlet. In between, the air likely follows a trajectory that is an average of the streamlines around it, although local differences may exist. The distance between individual "air molecules" is very, very small - but I wouldn't know exactly how small (and it will likely vary a lot, due to kinetic energy / the mix of various types of molecules / ...)
Good video! I have a suggestion, next time could you make a video that discuss about the aeorodynemics of aptera 3? (Just like when you discuss about the tesla semi truck aeorodynemics)

These series in this channel are amazing! Thank you so much for making this information simplified and accessible !
You're welcome!
Thank you Wouter for identifying the different measurement techniques.
You're welcome!

We just got a PIV system at work. Can't wait to get it up and running!
Ah great! Feel free to share your experiences here!

@@AirShaper luckily I got away with no permanent metal this time. thank you for this insight. I'll look into parametric 3D models, thanks again
Excellent, learning a lot!
Thanks a lot!!

is there air between the stream lines indicated via the smoke? what is the distance between the actual particles hitting an object in a wind tunnel?

We've contacted them for an interview - should it come through then we'll make a video on it!
that is so fucking cool wtf
