Exploration of the possibility of acoustic emission technique in detection and diagnosis of bubble formation and collapse in valves. IOSR Journal of Mechanical and Civil Engineering, Volume 13, Issue 6 Ver. II (Nov-Dec 2016), pp. 32-402320-334Xhttp://iosrjournals.org/iosr-jmce/pages/13(6)Version-2.htmlhttp://dspace.lib.cranfield.ac.uk/handle/1826/12855The application of acoustic emission (AE) technique in detection and monitoring of bubble formation and collapse in valves are presented in this review. The generation of AE signals and the basic compositions of AE detection system are briefly explained. The applications of AE technique in valves are focused on condition monitoring and detection bubble formation (bubble cavitation), and leakage of water through valves. All results prove that the AE technique works well for detection and diagnosis of failures during valves.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Article
