Eulerian–Lagrangian method for simulation of cloud cavitation [PDF]

open access: yesJournal of Computational Physics, 2018
We present a coupled Eulerian-Lagrangian method to simulate cloud cavitation in a compressible liquid. The method is designed to capture the strong, volumetric oscillations of each bubble and the bubble-scattered acoustics. The dynamics of the bubbly mixture is formulated using volume-averaged equations of motion. The continuous phase is discretized on

Influence of the Cavitation Model on the Simulation of Cloud Cavitation on 2D Foil Section [PDF]

open access: yesInternational Journal of Rotating Machinery, 2008
For numerical simulations of cavitating flows, many physical models are currently used. One approach is the void fraction transport equation‐based model including source terms for vaporization and condensation processes. Various source terms have been proposed by different researchers.

A numerical model for cloud cavitation based on bubble cluster [PDF]

open access: yesTheoretical and Applied Mechanics Letters, 2017
The cavitation cloud of different internal structures results in different collapse pressures owing to the interaction among bubbles. The internal structure of cloud cavitation is required to accurately predict collapse pressure.

Revealing the interplay between flow dynamics and cavitation activity in a flow-through sonoreactor [PDF]

open access: yesUltrasonics Sonochemistry
Acoustic cavitation is a well-known approach to intensify chemical and physical processes. Despite extensive studies in the understanding of batch ultrasonic reactors, flow-through sonoreactors, which are more relevant to continuous and large-scale ...

Control of Cloud Cavitation through Microbubbles [PDF]

open access: yesAustralasian Fluid Mechanics Conference (AFMC), 2020
The dynamics of cloud cavitation about a 3D hydrofoil are investigated experimentally in a cavitation tunnel with deplete, sparse and abundant freestream nuclei populations. The rectangular-planform, NACA0015 hydrofoil was tested at a Reynolds number of 1.4x10^6, an incidence of 6 deg and a cavitation number of 0.55.

Dynamics of cavity structures and wall-pressure fluctuations associated with shedding mechanism in unsteady sheet/cloud cavitating flows

open access: yesFlow, 2023
The physics and mechanism of sheet/cloud cavitation in a convergent–divergent channel are investigated using synchronized dynamic surface pressure measurement and high-speed imaging in a water tunnel to probe the cavity shedding mechanism.
