Annotation:

The mathematical basis for the calculation of nonstationary multiphase flows in the pump and airlift-based deep-sea hydrohoist is suggested. The authors obtained characteristic relations for the system of differential equations describing the motion of a two-phase and three-phase mixture in a pipeline using a new separate flow model. The approach to calculating the dynamics of multiphase flows opens up opportunities for designing deep-water pumping systems and analysis of their operational modes.
