Investigation was carried out on a swirl motion of a cylindrical bath agitated by a bottom blown liquid jet The nozzle was placed at an offcentered position Particular attention was paid to the boundary of the region in which the swirl motion appears, the period of the swirl motion, the transient period from the start of water injection to the occurrence of the swirl motion, and the transient period from the stoppage of water injection to the annihilation of the swirl motion The nozzle positon affected only the occurrence region of the swirl motion Empirical equations proposed for a centered nozzle were applicable to the other quantities for the off-centered nozzle
