Model investigation was experimentally made of transient liquid flow phenomena of stratified two liquid layers contained in a cylindrical vessel suddenly set in rotation. Transient flow in a baffled vessel was also mentioned to seek a possibility of rapid mixing and separation of molten slag and metal and to develop a novel refining process. The effects of the vessel size and the physical properties on the flow in the transient period were clarified. Particular attention was paid to a change in the interfacial area which is one of the most influential parameters for the refining process. Empirical equations were proposed for the flow establishment time.
