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 gen
Injection of bubbly gas flow into a liquid stream has wide application in chemical and biochemical industries. In these applications, generation of smaller bubble at higher frequency is desirable to achieve better reaction efficiency. We report on an
