AB - Cavitation is not only related with pressure, but also affected by  temperature. Under high temperature, temperature depression of liquids is  caused by latent heat of vaporization. The cavitation characteristics under  such condition are different from those under room temperature. The paper  focuses on thermodynamic cavitation based on the Rayleigh-Plesset equation  and modifies the mass transfer equation with fully consideration of the  thermodynamic effects and physical properties. To validate the modified  model, the external and internal flow fields, such as hydrofoil NACA0015 and  nozzle, are calculated, respectively. The hydro-foil NACA0015’s cavitation  characteristic is calculated by the modified model at different temperatures.  The pressure coefficient is found in accordance with the experimental data.  The nozzle cavitation under the thermodynamic condition is calculated and  compared with the experiment.
