Abstract
Swirling liquid jet is useful for agitating strongly a bath contained in a cylindrical vessel without using any mechanical devices such as an impeller in the bath. Many practical applications therefore are expected in a variety of fields such as materials, mechanical, chemical and food engineering. Swirling liquid jet can be generated by injecting a liquid into a cylindrical bath from a bottom nozzle. In this study, we introduce the flow visualization of a swirling liquid jet in a bath in two-phase stratification. We compare the experimental data of Particle Image Velocimetry (PIV) with the numerical results of Computational Fluid Dynamics (CFD).
