Abstract
In order to elucidate the gas jetting phenomena upon a liquid such as cavity formation and splashing of liquid, phenomenological fluid dynamical energy balance equation has been derived, where the total injection gas energy is the sum of a cavity potential energy and a cavity surface energy increase. A linear relationship between these energies per unit cavity volume and the injection gas energy density at the lance nozzle exit is observed and the effective energy coefficient for utilization for the inlet energy is derived as function of a dimensionless lance height. This paper also discusses the effects of surface tension and viscosity of a liquid as well as that of injection gas density on the cavity and splash formation mode.
