Orifice Coefficients Evaluation for Water Jet Applications
نویسندگان
چکیده
The topic of water jet orifices efficiency and effectiveness evaluation has been considered in this paper. The performed analysis is based on the evaluation of the discharge, velocity and contraction coefficients for different water orifices. In order to overcome the difficulty to measure the water velocity at the orifice exit, which can reach 900 m/s in case of pure water jet applications (without abrasive additives), a suitable laser Doppler measurement system has been applied. An analysis of orifice performances is presented in the present paper, also considering the case of broken orifices, very important for industrial applications.

The Velocity - Distribution in a Liquid - into - Liquid Jet
The distribution of velocity in a liquid-into-liquid jet, issuing from a cylindrical tube with a tapering approach, has been measured by photographing the traces made by suspended particles, with strong illumination and a determined exposure. The results have been compared with the theory for a jet issuing from a point in an infinite plane, and it is shown that, supposing the equivalent point s...
متن کاملA Jet Formation Criterion for Synthetic Jet Actuators
This paper proposes and validates a jet formation criterion for synthetic jet actuators. The synthetic jet is a zero net mass flux device, adding additional momentum but no mass to its surroundings. Jet formation is defined as a mean outward velocity along the jet axis and corresponds to the clear formation of shed vortices. It is shown that the synthetic jet formation is governed by the Strouh...
متن کاملVortex Formation with a Snapping Shrimp Claw
Snapping shrimp use one oversized claw to generate a cavitating high speed water jet for hunting, defence and communication. This work is an experimental investigation about the jet generation. Snapping shrimp (Alpheus-bellulus) were investigated by using an enlarged transparent model reproducing the closure of the snapper claw. Flow inside the model was studied using both High-Speed Particle I...
متن کاملQuantification of jet flow by momentum analysis. An in vitro color Doppler flow study.
Previous investigations have shown that the size of a regurgitant jet as assessed by color Doppler flow mapping is independently affected by the flow rate and velocity (or driving pressure) of the jet. Fluid dynamics theory predicts that jet momentum (given by the orifice flow rate multiplied by velocity) should best predict the appearance of the jet in the receiving chamber and also that this ...
متن کاملComparative Analysis of Turbulent Plane Jets from a Sharp-Edged Orifice, a Beveled-Edge Orifice and a Radially Contoured Nozzle
This article investigates through experiments the flow characteristics of plane jets from sharp-edged orifice-plate, beveled-edge and radially contoured nozzle. The first two configurations exhibit saddle-backed velocity profiles while the third shows a top-hat. A vena contracta is found for the jet emanating from orifice at x/h ≈ 3 while the contoured case displays a potential core extending t...
