About a cross-flow wind turbine with double circular arc blades, performance tests and flow visualization measurements at several operating points on the performance curves were done. The test model of cross-flow wind turbine showed the performance of parabolic curve and the highest power coefficient was at tip speed ratio λ=0.4. On several operating points of the cross-flow wind turbine, we tried flow visualization measurements of the smoke streamlines under two different photographic conditions of shutter speeds. We could observe the flow patterns changing with the operating condition and the vortex flow generating on the surface of a blade and released from the cross-flow wind turbine etc.
