Cavitation Bubbles in a Starting Submerged Water Jet [PDF]

open access: yes, 2001
The behavior of cavitation bubbles in a starting submerged water jet discharging from a circular nozzle is studied by a simple photography technique in a moderately low range of jet exit velocity.

Erosion and impact intensity of vibratory, jet and turbine cavitation [PDF]

open access: yes
The ratio of the cavitation erosion resistance of the new austenitic stainless steel Hydroloy to the one of the standard 308 has been found to vary from 11 to 16 in vibratory cavitation tests to about 5 in large hydroturbines. Cavitation erosion tests in

Partial Cavity Instabilities and Re-Entrant Jet [PDF]

open access: yes, 2001
The purpose of this talk is to give an overview of different instabilities which can affect partial cavitation. We shall focus on the case of a unique partial cavity attached to an isolated hydrofoil or to the throat of a Venturi. Another paper presented

Comparison of Cavitation Erosion Test Results Between Vibratory and Cavitating Jet Methods

open access: yesFluid Power Systems and Technology, 1992
Abstract The relationship of the test results between the vibratory and cavitating jet methods was clarified experimentally. Six types of metallic specimens which were made of aluminum alloy, superduralumin, high-strength brass, stainless steel, carbon steel and chrome-molybdenum steel were tested.

Cavitation erosion, impact intensity and pit size distribution of jet and vortex cavitation [PDF]

open access: yes
Three different methods of cavitation erosion measurement are compared and correlated with weight loss rates in two cavitation set-ups: a high-pressure cavitation jet producing a high repetition rate of a wide range of impact intensities and a single ...

Cavitation loading and erosion produced by a cavitating jet [PDF]

open access: yes, 1991
The aim of the project is to investigate the detail of cavitation loading and erosion process using a submerged jet cavitation technique. Large size cavitating jet apparatus in the University of Nottingham was used with an long orifice nozzle and experiments were carried out using tap water as a test liquid with upstream pressure ranging from 8D-120bar.
