Abstract
We have been groping for the possibility of using wined turbines in the city, by examine the way to harness wind energy near structures such as buildings. The wind turbine used here is a cross-flow wind turbine that has arc shaped blades with blade thickness. In this report we visualized near and inside the cross-flow wind turbine using a smoke visualization wind tunnel. We used two types of light sources (video light and strobe light), and two shutter speeds (1sec, 1/4000sec) to photograph the mean flow shot and snapshot. We compared visualization results with performance measurements at the same condition obtained previously.
