An experimental and analytical investigation was conducted for determining the rate of energy transfer from a relatively hot liquid to a relatively cool gas injected into the liquid through a submerged orifice, resulting in the periodic formation of discrete gas bubbles at the orifice. A preliminary investigation indicated that a significant amount of energy transfer occurs during the time of formation of the bubbles. Consequently, the investigation reported herein is concerned with the determination of the energy transfer from the liquid to the gas bubbles during the period of formation of the bubbles at the orifice.
