The Vortex Generator ("VG") is well known as an aerodynamic device that improves the velocity distribution inside the boundary layer. In this study, the effect of VGs inside the boundary layer on a flat plate was investigated by using the hot wire anemometer. In the experiments, the wake of VG was measured using a robotic arm. The measurement interval was 5 mm, and an X-type probe was used for the hot wire experiment. The uniform velocity of the wind tunnel is set at 20 m/s. The boundary layer thickness in the measurement plane is 60 mm. The velocity distribution in vertical Vz and spanwise Vy components are visualized.
