Hi everyone,
I am new and I hope I'm putting this in the right section. I am currently a Sophomore in High school and I am building a wind tunnel. It's not for a class but rather its is like an independent study. I have been into planes pretty much all my life and I am hoping to get a pilots license in the near future. In the meantime I am tiding myself over with some projects with airfoils with RC planes and to do that I want to build a wind tunnel.
I have looked all over the internet for information on this to try and not post and I have found one thread on this forum but it didn't answer all my questions. Hence I am here :)
I am following this guide: http://www.tririg.com/docs/CogganLSWT.pdf to base my wt off of. I have built the contraction cone and the test section so far. My major question is if I were to build this for testing RC plane wings how accurate would it be? I have researched the Reynolds number and I know that it is the relationship between viscous forces and inertial. The wind tunnel is basically a closed pipe so how should I go about testing velocity and quality of the flow? Are there any websites that you suggest I should look into? I am currently looking for aluminum honeycomb to straighten the flow and I am using window screens as a way to eliminate smaller turbulence.
Anyways, there is a lot of info but I would appreciate any help even if its just a small tip. Thank you so much!
