ON THE THEORETICAL PREDICTION OF CAVITATION INCEPTION

After a brief review of the traditional theoretical prediction methods,i.e.bubbledynamics method and pressure parameters method,this paper presents a new prediction method,called“fuzzy prediction method”.The new method consists of two predicting channels(analysischannel and empirical channel)and one scale-effect gate.It can not only give a reliable predic-tion result,but also,better than other method,predict cavitation type on the body.
