Abstract

Development of modern industrial process, especially gas – liquid, requires improvement of heat and mass transfer phenomena. One of the ways for such processes intensification is to increase the interfacial surface area and contact time by gas bubbling into liquid in form of micro-bubbles.Traditional bubble generation techniques rely on constant gas flow through a micro-porous bubble generating components which results in larger bubbles compare to a pore size. Modern micro-bubble generation techniques require high energy input for operation.Energy efficient bubble generation technique under oscillatory flow with use of the Tesař-Zimmerman fluidic oscillator has been investigated. Mesoporous diffuser has been tested in order to study single bubble and bubble cloud dynamics at different formation conditions. Bubble cloud dynamics have been observed using high speed photography to garner the bubble size distribution. The results of the study showed a significant drop in engendered bubble size when compared to constant flow approach.
