Study on Jet Formation and Modeling for High Pressure Abrasive Water-Jet
Key Engineering Materials, 2011 High pressure abrasive water jet (HPAWJ) machining has many advantages in hard brittle material processing. In this paper, the hole formation on stone by HPAWJ is analyzed based on brittle and plastic fracture theories. The formation and construction of jet are studied.

Nozzles Classification in a High Pressure Water Jet Systems
2007 IEEE Instrumentation & Measurement Technology Conference IMTC 2007, 2007In this paper, a technique for classifying the working condition of a water jet system is presented. The classifier is based on the DFT of the electrical power signal. It is shown that this information can characterize the working condition of the system and to predict the presence of (an incoming) faulty behaviour.

Cavitation in Submerged Water Jet at High Jet Pressure
Volume 2: Fora, 2015Recent industrial applications have unfolded a promising prospect for submerged water jet. Apart from widely acknowledged water jet properties, submerged water jet is characterized by the formation and complex evolution of cavitation bubbles. These bubbles not just alter the flow behavior of submerged water jet but also pose a profound effect upon ...

Crowning Carrots with a High Pressure Water Jet
Applied Engineering in Agriculture, 1988A crown trimming technique was investigated in an attempt to reduce the high produce loss associated with processing carrots. Carrot crowns have been cleanly trimmed at simulated rates as high as 20 t/h with the use of a high pressure water jet. The relationship between orifice diameter, carrot diameter, and water pressure necessary for an acceptable ...

High-pressure water jet injuries: a surgical emergency
Journal of Wound Care, 2000Injuries from high-pressure jet devices are surgical emergencies characterised by small entry wounds with extensive internal damage. Three factors are involved in these injuries. Physical injury can include local soft tissue disruption and vascular and nerve damage; chemical properties of the injectate can exacerbate compressive vascular injuries with
