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 jet pump area ratio,

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.

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 ...

Performance of a New Type of Water Jet Pump

Journal of Engineering for Industry, 1990
A new type of water jet pump called the bend-type jet pump was investigated both theoretically and experimentally for its performance, with the primary and secondary fluids both being water. The jet pump of this type with comparatively low area ratios is promising to transport liquid containing large particles.

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.

Jet Pump Cavitation With Ambient and High Temperature Water

Journal of Fluids Engineering, 1979
Cavitation characteristics of a jet pump were explored in tests with 80°C and 280°C water. A cavitation coefficient based on suction velocity and net suction head was used to correlate results. Results at low temperature compared well to results in literature.

Development of Jet Pumps for Boiling Water Reactor Recirculation Systems

Journal of Engineering for Power, 1974
The efficiency of jet pumps used in Boiling Water Reactors has been significantly improved through extensive development efforts. These jet pumps are used inside the reactor pressure vessel as part of the reactor recirculation system to circulate subcooled water at about 530 deg F. The development of the first-generation and improved, second-generation

High Speed Pumps in Water Jet Cutting

1992
In this paper we shall consider the possibilities of producing the high pressures required in water jet cutting / water jetting by using very fast rotating kinetic pumps. Such kinetic pumps require very little maintenance, they are light and small and no pressure accumulator is needed. Preliminary test results are included.
