  • Abstract The cavitation models are used to predict the dynamics of cavitation phenomenon. There are many tunable constants which is empirical-based in the cavitation models such as evaporation and condensation coefficient. Because of dynamic similarity issue, geometry change, turbulence models and other numerical details, there are various constants in different researches. In this paper, the dynamic similarity issue will be investigated and the sensitivity of the empirical constants and the interplay with turbulence models will be assessed by multiple steady attached and unsteady cloud cavitation problems in terms of experimental validations. The goal of this paper is to show the sensitivity and generality of the adjusted constants of different cavitation models.
