Water Jet Pump

Journal of the Hydraulics Division, 1964
The water jet pump, when designed with experimentally obtained optimum dimensions, can achieve efficiencies in the range of 35% to 40%. The design depends on the selected nozzles and diffuser, as well as the other parts of the pump, so that the hydraulic losses incurred are kept to a minimum.

Optimum Design of Water Jet Pumps

Journal of Engineering for Power, 1969
A summary of an extensive program of experimental and analytical work leading to a procedure for obtaining optimized performance of water jet-pump systems is presented. The procedure is extended to include systems involving n, series-staged ejector components operating in an optimal manner as a complete pump, pipeline, ejector unit.

Theory and Performance of Water Jet Pump

Journal of the Hydraulics Division, 1968
The theoretical maximum ideal pumping efficiency of a water jet pump is 50% at a flow ratio of unity. Pump performance can be predicted theoretically. With a pump designed with theoretically obtained optimum dimensions, a maximum efficiency of 39.8% was achieved. Efficiencies on the order of 42% could be obtained by selecting proper materials to reduce

Performances of Water Jet Propulsion with PD Pump

Applied Mechanics and Materials, 2014
Water jet propulsion (WJP) with positive displacement pump (PD pump), in which the suction thrust of PD pump (Due to the effect of pump suction and the influence of the suction boundary layer) and the reaction thrust of water jet are used to push watercraft forward, has many advantages like high efficiency,low noise, high maneuverability, good ...

Fault Classification Tool for High Pressure Water Jet Pumps

2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007, 2007
In this work a set of indexes able to define a suitable "footprint" of a Water jet system has been investigated. A on-line and non-intrusive monitoring and diagnostic system has been designed implementing an algorithm defined on the basis of the proposed indexes.

A configuration of the water-jet guided pump for the fiber laser

Laser Physics Letters, 2008
The water-jet guided pump (WJGP) is newly proposed to solve the serious thermal effects in high power end-pumped fiber lasers. In this pumping scheme, the pumping light is coupled into the water-jet similar to an optical fiber. The light is guided by the jet and pumped into a following fiber.

Maximum suction lift of water jet pumps

Journal of Mechanical Science and Technology, 2011
This paper describes an experimental study on water jet pumps with different diameters and nozzle-to-throat area ratios. The results revealed that the area ratio was an important parameter to characterize the maximum suction lift of the jet pumps, while their diameters had a negligible effect.

Optimization of water jet pumps using numerical simulation

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2013
A water jet pump is one of the best examples of a device in which liquid-jet mixing phenomena occur. Since such mixing processes are complex, the choice of turbulence model for accurate prediction of performance of the pumps is important. The aim of this numerical simulation study is to investigate effects of parameters such as the

Scale-resolving simulation of a water jet pump

Jet pumps are versatile hydraulic devices designed for displacing and/or mixing fluids. Scale-Resolving Simulations (SRS) of jet pumps are prohibitively expensive due to the presence of high Reynolds number flows and complex interactions within a wall-bounded domain.
