Unsteady cavitation characteristics of liquid nitrogen flows through venturi tube
TL;DR: In this article, the dynamic cavitation characteristics of liquid nitrogen flow through a transparent venturi tube are experimentally investigated in a variable pressure ratio tunnel, and the analysis on the measured dynamic pressure data and images reveal that the shedding frequency and length of cavity linearly increases, while the pressure amplitude exponentially increases, as the pressure ratio increases.

Experimental investigation of the global cavitation dynamic behavior in a venturi tube with special emphasis on the cavity length variation
TL;DR: In this article, the authors investigated the global cavitation behavior in a venturi tube and found that cavitation occurs each time regardless of the inlet or outlet pressure at the same critical pressure ratio of 0.89, which corresponds to a critical cavitation number of 1.99.

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.
