Rolling Road Wind Tunnel
We have a small rolling road for our wind tunnel. The test section is about 18″ x 12″ high and the rolling road is a modified belt sander. We added a 230vac3Ph variable speed drive and a bigger motor and took the belt sander from 10 mph up to 75 mph. We can do Particle Image Velocimetry (PIV) measurements in the tunnel. That is, it has the visual access for cameras and the laser.
