Numerical Analysis of the Turbulent Flow Structure Induced by the Cavitation Shedding using LES

Journal of Applied Fluid Mechanics, 2017
To analyze the interaction between the turbulent flow structure with the cavitation shedding dynamics, a three-dimensional unsteady cavitating turbulent flow around the three-dimension NACA009 hydrofoil is investigated in this study.

Cloud cavitation on an oscillating hydrofoil [PDF]

, 1994
Cloud cavitation, often formed by the breakdown of a sheet or vortex cavity, is believed to be responsible for much of the noise and erosion damage that occurs under cavitating conditions.

Cloud Cavitation Phenomena [PDF]

, 1999
This paper describes investigations of the dynamics and acoustics of clouds of cavitation bubbles. Recent experimental and computational findings show that the collapse of clouds of cavitating bubbles can involve the formation of bubbly shock waves and ...

Numerical analysis of the interactions of sheet cavitation and cloud cavitation around a hydrofoil

IOP Conference Series: Materials Science and Engineering, 2015
Partial cavitation and cloud cavitation on NACA66(MOD) was studied based on PANS turbulence model combined with the Zwart cavitation model. The results agree well with the data from the experimental results. The existence of a kind of unsteady characteristics of cloud cavitation is analysed in details.

Cavitation patterns on a plano-convex hydrofoil in a highspeed cryogenic cavitation tunnel [PDF]

, 2009
Cavitation around a plano-convex hydrofoil has been observed using a cryogenic cavitation tunnel of a blowdown type. An approximately 300mm long test section with flow visualization was set between the 100L upper and lower tanks.

The role of cavitation in submicron aerosol dispersion

MATEC Web of Conferences, 2018
Here we discuss the problem of atomizing submicron aerosols by special design atomizers enabling the cavitation regime. The formation of submicron aerosol was studied using an impulse atomizer model powered by a high-energy material and an atomizer model
