Experimental and Numerical Study of Cavitation Number Limitations for Hydrodynamic Cavitation Inception Prediction

Hydrodynamic cavitation is the formation, growth and subsequent collapse of vapor bubbles in a moving liquid. It extremely important to determine conditions inception when it starts damaging industrial equipment. In some cases, such as hydrodynamic cleaning understand how improve phenomenon order enhance properties. The number parameter used predict its potential effects. this paper we discuss limitations demonstrate that cannot be considered sufficient development fluid flow. experimental setup was designed built study various nozzles. RANS SST k–? turbulence model turbulent flow ANSYS Fluent. CFD calculations were compared results. shown sensitive change nozzle geometry and, since geometrical parameters are not included formula, scenarios can different at same number.
