Abstract

Bubble formation from a centered single-hole nozzle placed on the bottom of a water bath has been investigated using a high-speed video camera. Wetted and poorly wetted nozzles are used to understand the effect of wettability of nozzle on the bubble formation in the water. When the gas flow rate is lower than a certain critical value, the frequency of bubble formation is specified by the outer nozzle diameter. On the other hand, when the gas flow rate is raised above another critical value, the inner nozzle diameter governs the bubble formation. An empirical equation is proposed for the frequency of bubble formation in the water.
