Latest project, wind tunnel and a plasma actuator

I'm building a wind tunnel in my garage. Doesn't that sound neat? My interest in this is probably obvious because of several posts that I have dome thus far related to Plasma Actuators. The experiments that I was doing with my homemade Schlieren setup and specifically the high voltage experiments HERE and HERE among others.
The idea is to build a wind tunnel and place a plasma actuator inside it and watch what happens as the air is passing over the actuator. Comparing it in the 'on' and 'off ' states and various voltages. The wind tunnel has two windows so I can put the Schlieren setup on each side. Additionally I want to use a smoke generator and lasers to visualize the airflow. Check out THIS video to see what I mean about the lasers and smoke.
What does all this mean? I ask myself that question frequently, hourly sometimes but the answer is "I don't know!" That is why I am taking the time to build this setup and because it's a rather complicated project I don't have any neat pictures and videos to post yet but stay tuned they are on their way. The wind tunnel by itself is a significant amount of work and of course the plasma actuators are too. A lot of work and the devil is in the details so I'm paying attention to them (more or less).
After having read everything that I can about both wind tunnels and plasma actuators I have some specific things that I want to try. I'll detail each of those in the next week or two and post some neat pictures and videos.
