A theoretical analysis and an experimental study on the efficiency of water jet pumps, where water is used for both the primary and secondary flows, are presented in this paper. The theoretical efficiency equations for such jet pumps were first derived based on one-dimensional formulation, and the theoretical maximum ideal efficiency of 100% was ...

It is suggested that determination of the efficiency of a jet pump be formulated as a function of the configuration of the hydraulic system. For three configurations of a system proposed for pumping liquid from one tank to another, the dependence of the efficiency on the coefficient of injection and the relative dimensions of the nozzle is presented in

A PUMP designed to operate with corrosive liquids at extremely high temperatures will usually be constructed from refractory oxides and hence, if possible, must not rely on solid moving parts such as valves, pistons and rotors. A simple method of achieving this is to make use of some non-reciprocal hydrodynamic effect.

A micromachined vapor jet pump
Sensors and Actuators A: Physical, 2005Abstract Initial results from a micro-pump based on the principle of macroscopic vapor-jet- and diffusion-pumps are presented. A mathematical description of the underlying gas dynamics is given and equations for the calculation of pump geometry are derived. Several planar micro-vapor jet pumps with different geometries were designed and fabricated by

Centrifugal Jet-Pump Combinations
Journal of Fluids Engineering, 1952Abstract The widespread use of the water jet combined with a centrifugal pump to create what is commonly called a “jet pump” for domestic water systems, directs attention to the determination of its operating characteristics in terms of its components. The relative importance of this type of pumping equipment is illustrated by Department

Fundamentals of Oilwell Jet Pumping
SPE Production Engineering, 1988Summary This paper explains the theory behind the operation of jet pumps, including the effect of density differences between power fluid and produced fluids. By differentiating between the pump intake pressure and the throat-entrance pressure, we provide insight into the factors that affect jet pump performance.
