底吹き液体噴流によって攪拌される二層成層円筒浴の旋回運動の周期と振幅 Period and Amplitude of Swirl Motion of Stratified Cylindrical Bath Agitated by Bottom Blowing Liquid Jet
Cold model experiments were carried out to understand the period and amplitude of swirl motions of a molten steel jet generated through a centered bottom nozzle. Cylindrical vessels of three different diameters were chosen. Water and silicone oil were used as the working fluids. Two types of swirl motions were observed. One appeared when the silicone oil layer was thin, and the water and silicone oil rotated in phase with each other. The other appeared at the interface between the two liquid layers when the silicone oil layer was thick. Empirical equations were proposed for the period and amplitude of the two types of swirl motions.
