RESIDUAL TURBIDITY IN HYDRAULIC JET FLOCCULATORS

ISH Journal of Hydraulic Engineering, 2009
ABSTRACT Removal of turbidity from water supply systems is an important aspect of water treatment works. In this study the efficacy of free jets for flocculation is examined. It was observed that depth of submergence of the nozzle had very little effect on the degree of mixing.

The influence of impinging jets on hydraulic jumps

Proceedings of the Institution of Civil Engineers - Water Management, 2004
Experiments were carried out in a horizontal channel with a free jump and jumps with jets introduced at various angles. Particles within the jumps were traced using a high-speed video camera and the images were processed using a computer to determine particle velocities within the jumps.

Hydraulic Jump Assisted by Cross-Jet

Journal of the Hydraulics Division, 1971
A new method of controlling a hydraulic jump is developed herein. Utilizing a submerged cross-jet, instead of solid chute blocks and baffle piers, to furrow and lift the supercritical approaching flow, a hydraulic jump is produced which requires a smaller tailwater depth and provides greater energy dissipation.

Hydraulic Jet Propulsion: A Theoretical and Experimental Investigation into the Propulsion of Seacraft by Water Jets

Proceedings of the Institution of Mechanical Engineers, 1963
In recent years there has been a revival of interest in hydraulic jet propulsion as a means of propulsion for seacraft. In this paper the important design variables for this type of system are established and the theoretical relationships between them derived.

TEST OF HYDRAULIC JET PUMP IN THE BALAM 91 WELL

Proceedings of SPE International Petroleum Conference and Exhibition in Mexico, 2000
Abstract When the natural energy of a reservoir is not enough in order to elevate the oil to the surface, it is necessary to use an artificial lift system that supply the additional energy required to continue the exploitation of the reservoir. Likewise, the artificial lift system is installed to increment the production in flowing wells.

OPTIMIZATION OF JET-BIT HYDRAULICS USING IMPACT PRESSURE

Proceedings of SPE Annual Technical Conference and Exhibition, 1979
Abstract Bit hydraulic horsepower, impact force, and nozzle velocity are common criteria for optimizing jet-bit hydraulics. In this paper, a new improved criterion and technique based on maximum impact pressure is proposed.

Wall Jet Analogy to Hydraulic Jump

Journal of the Hydraulics Division, 1975
Hydraulic jump on horizontal bed of a rectangular channel is treated as a plane turbulent wall jet of an incompressible fluid of finite width in adverse pressure gradient. Momentum integral techniques have been applied to determine the longitudinal variations of the parameters characterizing the assumed mean velocity distribution.

Hydraulic Performance of an Annular Plunging Jet Reactor

Chemical Engineering Research and Design, 2002
Agas-liquid reactor is described, in which a plunging jet issues into a confined downcomer column, entraining headspace gas as it impinges onto the surface of a receiving pool of the same liquid. The two-phase mixture flows down the confining column and then rises through a concentric annulus, before disengaging in a separation vessel.

Hydraulic Design of Hollow-Jet Stilling Basins

Journal of the Hydraulics Division, 1961
Hydraulic model and prototype tests made to generalize and prove the hydraulic design of a new type of stilling basic which utilizes the hollow-jet valve for discharge control are described. Dimensionless curves are derived from model data and are used to define the important dimensions of the basin for the usual combinations of valve size, operating ...

HYDRAULIC JET PUMPING AT TINTABURRA OILFIELD

The APPEA Journal, 1988
The Hutton zone of the Tintaburra oilfield has an active bottom water drive which necessitates high gross fluid production rates to enable reserves to be produced within a reasonable period of time. A high volume artificial lift system capable of producing 8 000 to 10 000 barrels of fluid per day (BFPD) from 6 producing wells formed the basic design ...
