The bubbling of liquid with gases is required in a number of important industrial processes such as; gas–liquid contactor, gas–liquid separator, bubble absorption, bubble column, fermentation, metallurgy and waste water treatment. The size of generated bubbles has a significant effect on the hydrodynamics and mass transfer performance in these technological processes. In the present experimental study an innovative nozzle design for reducing the size of bubbles generated in stagnant liquid, at constant gas flow conditions, was tested and evaluated for two nozzles diameter as well as different gas flow rates. This technique is based on the creation of one or two side holes in the nozzle near the main nozzle hole so that the diameter of these side holes is lower than the inner nozzle diameter. Results show that the new nozzle design produced smaller bubbles with higher detachment frequency in comparison with those bubbles generated from the standard nozzle with no side holes.
