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

CLOUD CAVITATION DYNAMICS [PDF]
The ANZIAM Journal, 2008 AbstractAn analysis is developed for the behaviour of a cloud of cavitation bubbles during both the growth and collapse phases. The theory is based on a multipole method exploiting a modified variational principle developed by Miles [“Nonlinear surface waves in closed basins”, J. Fluid Mech.75 (1976) 418–448] for water waves.

Similarity Law on Shedding Frequency of Cavitation Cloud Induced by a Cavitating Jet
Journal of Fluid Science and Technology, 2012 In order to clarify the mechanism of cavitation cloud shedding, the shedding frequencies of cavitation clouds were investigated by high-speed observations and image analysis. The results indicate that the shedding frequency follows the similarity law for

Control of Cloud Cavitation through Microbubbles [PDF]
Australasian 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.
