To improve the simulation accuracy of hydrofoil unsteady cavitation, a user-defined density
function is used to correct a variety of turbulence models and combined with a hydrofoil with …

The vortex structure is a typically coherent structure. The influence of hydrofoil jets with
different chordal positions on the vortex structure in the hydrofoil flow field is investigated to …

The objective of this work is to investigate experimentally controlling cavitating flow over
NACA66 (MOD) hydrofoils by means of an active water injection along its suction surface …

Cavitation is an unsteady complex turbulent flow phenomenon that increases the resistance
of propellers and hydrofoils, reduces hydrodynamic efficiency, and erodes surfaces …

Cavitation is a complex and unsteady phenomenon. When the cavity generated at the
leading edge extends to the trailing edge, a cloud/supercavitation phenomenon appears …

We studied cavitating flow over the suction side of two symmetric 2D foils–a NACA0015
hydrofoil and a scaled-down model of high-pressure hydroturbine guide vanes (GV)–in …

Partial cavitation is one of the main cavitation regimes occurring in hydrofoil sections. In this
study, the effect of gradually increasing and decreasing the angle of attack (α) on partial …

Highlights•The modified Rayleigh equation is integrated to obtain the bubble wall
velocities.•The coupling strength during the evaporation and condensation are different.•The …

A method of water injection to flow field using distributed holes on the suction surface of
hydrofoil is presented in this article to control cavitation flow. Modified renormalization group …

The paper presents the results of a cavitation in a slit channel study and offers an analytical
description of cavity development. Special emphasis was placed on examining partial …
