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

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

, 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.

Geometric reduction of jet cavitation erosion and quantitative measurement of solid-surface damage

Journal of Advanced Mechanical Design, Systems, and Manufacturing
Impingement of a cavitating jet on a solid surface causes erosion, resulting in problems in fluid machinery. To avoid degradation and breakdown of the machinery, cavitation erosion must be reduced, and the erosion damage should be estimated.
