Acoustic Diagnostics of Underwater Emissions Propagating in the Form of a Multiphase Jet

The interaction of a pressure pulse with a gas-liquid zone, which is a section of a flooded multiphase jet consisting of a mixture of water and oil and containing a bubble core of methane, is numerically investigated. The possibility of determining the degree of expansion of the jet, the volume content of oil and gas in the jet from reflected signals is shown.
