An experimental investigation of artificial supercavitation generated by air injection behind disk-shaped cavitators

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2017
In this paper, we investigated physical characteristics of an artificial supercavity generated behind an axisymmetric cavitator. Experiments for the same model were carried out at two different cavitation tunnels of the Chungnam National University and ...

Cavitation Light Emission and Cavitation Erosion

open access: yesJournal of The Japan Institute of Marine Engineering, 2008
Cavitation bubbles emit a very weak light due to bubble collapse. It is expected that the light emission may be closely related to cavitation erosion. In order to confirm the relationship between the erosion damage rate and the light intensity, experiments were performed for a water orifice cavitation flow. A circular pipe was used and water-cavitation

Numerical study of the hydrodynamics of supercavitation flow around an underwater body [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика
The work is devoted to the study of the high-speed flow around an elongated body in water at various depths in the supercavitation regime. The aim of the research is to study the state of the environment around a submerged body and the possible influence

Supercavitating Vehicles With Noncylindrical, Nonsymmetric Cavities: Dynamics and Instabilities

open access: yes, 2011
Cavity-wall interactions play an important role in determining the dynamics of supercavitating vehicles. To date, supercavitating vehicle system models make use of constant cylindrical cavities.

Numerical Simulation of Water Entry Process of Trans-Medium Vehicles

open access: yes水下无人系统学报
The trans-medium water entry process of vehicles is often accompanied by multiphase flow, cavitation, phase change, and turbulence instability, which not only heighten the complexity of the flow field, but also render the forces highly unsteady and ...

Cleaning method of working volumes of hydraulic cylinders of agricultural machines without preliminary dismantling

open access: yesSiberian Journal of Life Sciences and Agriculture
Background.  More and more often lifting equipment is equipped with a hydraulic drive, which allows to develop the highest tractive force. However, this type of drive is prone to a reduction in the speed of the mechanism due to possible clogging of the ...
