Analysis of the effects of turbulence modeling on the numerical simulation of unsteady sheet cavitation
Mathematical derivation of the equations currently used in CFD of cavitation, with underlying assumptions including the notion of “two-phase fluid particle”
Theoretical and numerical comparison of the existing cavitation models, showing how similar the models are, despite their various formulations
Analysis of the stability of the preconditioned Navier-Stokes equations associated with a cavitation model
Physical analysis of rotating cavitation in rocket engine inducers
Coupling of CFD simulation and erosion model to predict the damage due to cavitation erosion
Development and validation of fast X-ray imaging (including data acquisition, image post-processing and validation) for simultaneous measurement of void fraction and velocities in both phases. Analysis of the structure and dynamics of cavitating flows
