In order to elucidate the gas jetting phenomena upon a liquid such as a cavity formation and splashing of liquid, an energy balance equation has been derived, where the total gas cavity energy is the sum of a cavity potential energy and a cavity surface energy increment. A linear relationship between those sum per unit cavity volume and the energy density at the nozzle lance exit over liquid were observed and the effective energy coefficient for utilization for inlet energy has been derived as a function of a dimensionless lance height. This paper also discuss the effects of surface tension and viscosity of a liquid as well as that of inlet gas over cavity formation behavior and splashing caused by gas jetting over a liquid.
