Cavitation Detection In a Water Jet Propulsion Unit

摘要

Various sensing and digital signal processing approaches to detect cavitation in a water jet propulsion unit were examined based on results in the literature. Several commercially viable sensors were evaluated based upon their ability to detect the cavitation phenomenon, cost, and robustness. An algorithm has been implemented and tested against data recorded from the candidate sensors. The combination of vibration and pressure sensors and the algorithm appear promising and a path for further development and testing is available to Hamilton Jet.
