This paper presents a discussion of the physics of the flow discussed in the first report (Shimizu, Y. et al., 1990). By visualizing the flow around the tip vane, the following results were drawn: (1) The strength of the tip vortex, the induced drag and turbulence on the blade tip can be diminished with a tip vane. (2) The inflow rate to the rotary surface of wind turbine can be increased with the tip vane.
