In order to control the vortex structure within a turbulent boundary layer, the small vortex generating jet was applied. The visualization and analysis of a generating vortex in each jet conditions by the laser light sheet method using YAG laser were performed. Moreover, comparison with the speed distribution measured using the hot wire flow velocity meter performed before was carried out. It turns out that the vortex by which the time of jet angle α=45° was stabilized most is generated from this result.
