Horizontal gas injection is commonly used in the refining processes such as the desulphurization process and AOD process. This paper deals experimentally with wave motions in a water-filled cylindrical bath into which air is injected through a L-shaped lance placed at the bath centerline. Experiments are made on the patterns of wave motions on the bath surface. The wave motions of a bubbling jet are observed by eye inspection and with a digital video camera from the side and top of the vessel. It is found that a swirl motion appears as one of the wave motions under a certain condition. In this study, we further focus on the occurrence condition of a deep-water wave type swirl motion, swirl period and amplitude. The measured values are compared with empirical and theoretical equations proposed previously for the bottom blown bath.
