Science Buddies: "Ask an Expert"

Hi guys, new person here.

Just wanted to ask what you guys would recommend to use in a wind tunnel (low-speed, Low-cost). I was thinking about using streamers or even special colored smoke, but both of those have issues. I want to use them to track air turbulence around a structure, their eddies, and vortices.

My (original, but inspired) idea is to use a wind tunnel and light and flexible little structures to try to find what building design avoids the most vibration and the most air turbulence

Hi LifeOnMars,

The following project suggests using streamers for visualizing air flow in a wind tunnel:

You might want to take a look at the some of the references in the background section of the project for some additional ideas.

I hope this helps. Please ask again if you have more questions.
