Abstract Hydrodynamic cavitation is an extensive fluid mechanical phenomenon in rotating machines such as hydraulic machinery and hydraulic system. The micro-lubricating film is formed by dynamic pressure effect between fluid film lubricated mechanical face seals used in rotating machines. The cavitation of micro-scale fluid film between seal faces plays an important role in the performance of mechanical seals, which has become one of the hot issues of mechanical seal research. In order to grasp research directions in the future, the cavitation issue in mechanical seals was overviewd from the aspects of cavitation mechanism, experimental research and theoretical research. The progress of macroscopic cavitation, micro cavitation, cavitation boundary conditions and algorithms was analyzed synthetically. Subsequently, the future research directions of mechanical seals cavitation are proposed, which includes cavitation theoretical model, numerical simulation technology, new cavitation control technology and effective measurement technology.
