The impact of cavitation erosion behavior on different metals in a water flowing system was investigated experimentally. A built and transparent observation window is designed to capture the flow. Erosion tests were carried out red copper, brass, pure aluminum, an aluminum alloy. behaviors are presented by weight loss rate, related changes topography metal surface also discussed. variation meta...

Cavitation damage to membranes is a major barrier for developing an ultrasound (US)-assisted membrane water treatment process. In this study, US was integrated heterogeneous Fenton reactor the of pharmaceutical-containing with aims i) fouling control, ii) enhancement oxidation. order prevent damages due cavitation, stable and violent cavitation regions were identified by quantification analysis...

Cavitation is a physical process that produces complex effects on the machines and components working in conditions where it acts. One effect materials-mass loss by corrosion–erosion when are introduced into fluids under cavitation. The analysis of damages produced cavitation generally performed using different destructive non-destructive experimental techniques. Most studies materials’ behavio...

Cleaning and erosion of objects by ultrasound in liquids are caused by the action of acoustic cavitation bubbles. Experiments have been performed with respect to the erosive effect of multibubble structures on painted glass surfaces and on aluminium foils in an ultrasonic standing wave field at 40 kHz. High-speed imaging techniques have been employed to investigate the mechanisms at work, in pa...
