Transient Flow Analysis of Stratified Two Liquid Layers Contained in Rotating Cylindrical Vessel

Abstract

Experimental and numerical investigations were carried out on the transient behaviors of stratified two liquid layers contained in a cylindrical vessel suddenly set in rotation. Particular attention was paid to the deformation of the free surface and that of the interface between the two liquid layers. This flow field is a primary model for the formation of a plume eye on the surface of a bottom blown bath covered with a top slag layer. The numerical result could satisfactorily predict the time-dependent contours of the free surface and the interface. This mathematical model is also useful for the prediction of the interfacial area between molten metal and slag in a promising novel refining process using a suddenly rotating cylindrical vessel.
