Abstract

An interface between stratified two liquids contained in a cylindrical vessel rotated around the vertical vessel axis when a bottom blown jet of the lower liquid impinged on the interface. This swirl motion has high mixing intensity, and hence, is useful for enhancing mass transfer at the interface. A critical condition for the occurrence of the swirl motion was experimentally investigated. Empirical equations proposed originally for predicting the critical occurrence condition of a swirl motion in a single-liquid bath were applicable to this case by replacing the gravitational acceleration constant by a modified gravitational acceleration one.
