20.500.12556/RUL-114853 Simplified detection of cavitation threshold in control valves For industrial monitoring of fluid flows, the transition from a single-phase flow to a cavitation regime is most commonly determined by a microphone that measures the sound emitted in the vicinity of critical constrictions such as in the opening of the control valves. To measure the cavitation threshold, we developed an analogue and robust piezoelectric detection method. The evaluation of this method on the reference test orifice plate and on a chosen control valve shows that it eliminates the sound noise of an industrial environment, largely removes the subjectivity of the operator and enables a more detailed observation of the cavitation phenomenon. cavitation cavitation threshold piezoelectric sensors acoustic emission nondestructive testings control valve cavitation evaluation kavitacija kavitacijski prag piezoelektrični senzorji akustična emisija nedestruktivna testiranja true false false Angleški jezik Slovenski jezik Članek v reviji 2020-03-20 07:21:12 2020-03-20 07:21:17 2023-07-26 11:41:42 0000-00-00 00:00:00 2020 0 0 6 str.
