Not sure if this is the best place for this but I thought I might try and some people might be interested.
My A2 physics coursework requires a free choice 'open-ended' coursework investigation. For this I chose to design and build a small wind tunnel which I have completed myself. I have done a few test with balsa aerofoil shapes measuring the increase in mass on a small set of scales and it seems to work quite well.
Due to the open ended requirement, I really need to think about as many things to test and measure as possible. The working section is quite small at 100x100mm but the speed is decent (as of yet properly measured). I understand I am no expert and I have many limitations given the nature of the project but If anyone has any ideas or questions that would be great
If not then hey, I built a wind tunnel and here's a picture...
