Evaluations of the outcome variability of RANS simulations for marine propellers due to tunable parameters of cavitation models
TL;DR: The methodology of the Cavitation Occurrence Probability (COP) is used to resolve the second issue and evaluate the outcome variability due to the tunable parameters of three popular cavitation models, i.e. the Full Cavitation Model, Zwart-Gerber-Belamri (Z-G-B) and Schnerr-Sauer (S–S) models.

Some notes on numerical simulation and error analyses of the attached turbulent cavitating flow by LES
TL;DR: In this article, the authors investigated the effect of cavitation on the numerical simulation of large eddy simulation (LES) for the unsteady cavitation simulation and showed that cavitation can extend the magnitudes and oscillation levels of numerical error and modeling error.

Experimental studies of hysteresis behavior of partial cavitation around NACA0015 hydrofoil
TL;DR: In this article, the effect of gradually increasing and decreasing the angle of attack (α) on partial cavitation of hydrofoils, has been investigated, and a new hysteresis phenomenon is observed in a difference of partial cavity length in increasing or decreasing of α.

Investigation of Cavitation Noise in Cavitating Flows around an NACA0015 Hydrofoil
TL;DR: In this paper, a modified turbulence model and Zwart cavitation model were employed to calculate the flow field and predict the cavitation phenomenon accurately, then, the acoustic analogy method based on the Ffowcs Williams-Hawking (FW-H) equation was applied to analyze the Cavitation-induced noise.

Eddies Stream, and Convergence Zones in Turbulent Flows
TL;DR: In this article, a set of objective criteria were found which describe regions in which the streamlines circulate, converge, or diverge, and form high streams of high velocity flow.

A new modelling of cavitating flows : a numerical study of unsteady cavitation on a hydrofoil section
TL;DR: In this paper, a bubble two-phase flow (BTF) model is proposed to explain the interaction between viscous effects including vortices and cavitation bubbles, which treats the inside and outside of a cavity as one continuum by regarding the cavity as a compressible viscous fluid whose density changes greatly.
