Swirl Motion of Insoluble Liquid Jet in a Cylindrical Bath of Stratified Two Layers
Jin Yoshida, Yoshiaki Ueda and Manabu Iguchi
A new extraction process using a swirling liquid jet was proposed. An interface between stratified two liquid layers exhibited a swirl motion due to impingement of a bottom blown jet on the interface. Mass transfer between the two layers is expected to be highly enhanced in the presence of the swirl motion. The boundary for the occurrence of the swirl motion was correlated in terms of the aspect ratio of the lower liquid layer and a modified Rossby number based on the stratification parameter. The swirl period was approximated by an analytical equation for the period of rotary sloshing.
