Mist Flow Visualization for Round Jets in Aerosol Jet Printing

open access: yes, 2018
With the microdroplets of water serving as light scattering particles, the mist flow patterns of round micro-jets can be visualized using the Aerosol Jet(R) direct-write system. The visualization images show that the laminar mist jet appears to extend to

A Novel Cutting Technology for Chemical Environments Using Pulsed Abrasive Water Jet

open access: yesChemical Engineering Transactions, 2017
This paper aims to apply the self-excited oscillation pulsed (SEOP) water jet to metal cutting in chemical environments. For this purpose, the impact force of the water jet was compared with that of continuous jet under different flow pressures and at ...

Sensitive Water Jets [PDF]

open access: yesNature, 1892
A FORM of this effect lately presented itself, which seemed in some ways new. A thin jet, 5 feet high and arched so as to be 3 feet at the base, was falling in a feathery spray. At 13 feet distance a small Wimshurst machine was set going: not instantly, but after two minutes, the spray gathered itself up almost into one clear line: although the jet was

Experimental study of Counter-Rotating Vortex Pair Trajectories induced by a Round Jet in Cross-Flow at Low Velocity Ratios

open access: yes, 2013
Circular flush Jets In Cross-Flow were experimentally studied in a water tunnel using Volumetric Particle Tracking Velocimetry, for a range of jet to cross-flow velocity ratios, r, from 0.5 to 3, jet exit diameters $d$ from 0.8 cm to 1 cm and cross-flow ...

Numerical simulations of non-spherical bubble collapse [PDF]

open access: yes, 2009
A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...

Study on the optimal parameter matching model of rotary cutting coal-rock for abrasive water jet

open access: yesMeitan kexue jishu
As coal mining extends deeper, pure water jet technology is gradually unable to meet the demand for coal penetration enhancement under high stress and high coal rock strength conditions.

Cavitation Induction by Projectile Impacting on a Water Jet [PDF]

open access: yes, 2019
The present paper focuses on the simulation of the high-velocity impact of a projectile impacting on a water-jet, causing the onset, development and collapse of cavitation. The simulation of the fluid motion is carried out using an explicit, compressible,
