Modeling and Design of jet pumps

Abstract

Models for jet pumps currently are derived under the assumption that the power and well fluids are incompressible liquids that, in many cases, are assumed to have equal densities: When either the well or the power fluid contains gas, current design practices still use the equations for incompressible liquids and account for the presence of gas by modifying the mass-flow-rate ratio and the friction-loss coefficients. This paper proposes a new approach to modeling pumps operating under multiphase-flow conditions.
