Prediction of the 2-d Unsteady Supercavity Shapes

open access: yes, 2001
A method to calculate a length and a shape of two--dimensional unsteady supercavities past slender wedges and around slender hydrofoils is developed. In case of arbitrary time--dependence, the finite difference time discretization is used. In each time

Investigation of Internal Flow Velocity Distribution and Gas Loss of High-Speed Supercavitating Flows

open access: yes, 2017
Internal velocity distribution is an important content of flow structure and reveals the gas loss mechanism for supercavitating flows. Considering the three-phase momentum interactions and the water-vapor mass transport, the water-gas-vapor multi-fluid ...

Ventilated supercavitating hydrofoils for ride control of high-speed craft

open access: yes, 2011
An investigation into the hydrodynamic performance and flow field characteristics of a novel high-speed supercavitating hydrofoil concept proposed by Elms (1999) is presented.

Investigation of the behavior of ventilated supercavities [PDF]

open access: yes, 2009
The topic of supercavitation is of considerable interest to drag reduction and/or speed augmentation in marine vehicles. Supercavitating vehicles need to be supplied with an artificial cavity through ventilation until they accelerate to conditions at ...

Closure mechanisms of ventilated supercavities under steady and unsteady flows

open access: yesJournal of Physics: Conference Series, 2015
The present work reports some interesting experimental results for ventilated supercavitation in steady and unsteady flows. First, a variety of closure modes obtained as a result of systematic variation in Froude number and air entrainment, are reported. The closure mechanisms were found to differ from the standard criterion reported in the literature.

Study of the self noise generated by supercavitating vehicles [PDF]

open access: yes, 2016
This study investigates the self noise from a ventilated supercavitating vehicle. A ventilated supercavity is a gaseous envelope surrounding an underwater vehicle that significantly reduces the drag felt by the vehicle.
