Vortex generators are used as effective controllers of aerodynamic characteristics of industry equipments. But full knowledge of their mechanism is not attainable due to complex interaction between shedding vortices and bodies. This study focuses on an investigation of flow patterns from simple vortex generators by LDV measurements and smoke wire visualization. Circular cylinder is adopted for preliminary examination of velocity wake patterns and three kinds of generator shapes and two kinds of gap angles for their generator were tested in a wind tunnel. As experimental results, quite different wake patterns and velocity distribution within the wake region are observed.
