Abstract In view of the thermodynamic effects of cavitation of different fluid media in the inducer, the theoretical, experimental and numerical simulations are summarized. In the aspect of theoretical research,the formation mechanism and the relevant parameters characterizing the cavitation thermodynamic effect are introduced in detail. It is pointed out that the development direction of theoretical research is to deeply explore the dynamic characteristics and relevant mechanisms of the thermodynamic effects of cavitation in cryogenic media. In the aspect of experimental study, the research progress of the cavitation thermodynamic effect of different fluids in an inducer is reviewed in detail. It is pointed out that the unsteady state visualization test of cryogenic media in the inducer is the future research direction. The numerical simulation of the cavitation thermodynamic effect is discussed in terms of the cavitation and turbulence models, which is providing a detailed analysis of the numerical simulation of the cavitation thermodynamic effect of different fluid media in the inducer. It is considered that the quantitatively study the effect of thermodynamic effects on different cavitation forms is one of the deve-lopment directions in the furfure. Finally, based on the current research situation of cavitation thermodynamic effects of different fluids in the inducer, the development direction is discussed and prospected.
