Abstract

A theoretical analysis of critical parameters determining the heights at which a qualitative change in the flow of the jet takes place is carried out: the specific impulse of the buoyancy force begins to exceed the specific impulse acquired by the jet at the beginning, the separation of bubbles from the jet begins, the jet turns into a plume. A jet consisting of oil and gas bubbles on which the flow of the surrounding water acts is considered. The results obtained were tested on the initial parameters of the system, corresponding to the experiment, and the jet trajectory was also compared with the experiment.
