The dynamics of gas jets expelled into liquid are investigated utilizing Computational Fluid Dynamics (CFD). Results are analyzed with respect to changes in external liquid velocity and mass flow rate of the gaseous jet. In order categorize the complicated nature of the gas-fluid interactions coupled with the many physical dependencies, a flow-regime map is created. The majority of the regimes result in the formation of gaseous cavities encasing the jet, of which forms several cavity types. The internal flow structure of the categorized regimes are then studied with respect to the jet interactions with surrounding liquid and formed cavities. The results show major regions of recirculation and that the jet acts as a confined jet.
