Numerical Evaluation of Cavitating Flows Using Different Two-Phase Models

This paper focuses on the modeling of cavitating flows by means of a barotropic law of state. Within a robust 2D Navier-Stokes, capable to handle the complex aspects of cavitating flows, different cavitation models are implemented. In particular two different classes of barotropic cavitation models have been used: a sinusoidal model and a quasi-homogeneous isenthalpic cavitation model suitably modified to account for thermal effects. The paper deals with the differences between these models and hence with the differences with the resulting flow fields. The analysis has been made for the flow over an ogival headform.
