Stokes wave over cavitating vortex
نویسنده
چکیده
Following Stokes, several authors have studied waves with 120-degree angles at their crests caused on a free surface of fluid by the gravity force. Mathematical analysis, however, shown that similar Stokes waves can be caused by centrifugal force on surfaces where the pressure is constant, and cavitating tip vortex can be examined as a surface of an eventual appearance of axissymmetrical Stokes waves. Determination of shape of such vortices is a novel non-linear problem in potential theory. Thus, a special attention is paid to successive validation of intermediate computations. The main characteristics of the cavity-wave couples past a semi-ellipsoid are computed. An attempt to establish an association between the considered utmost steady flow and experimental data related to breakdown of cavitating vortices is done.

In the present paper, partial cavitation over various head-forms was studied numerically to predict the shape of the cavity. Navier-Stokes equations in addition to an advection equation for vapor volume fraction were solved. Mass transfer between the phases was modeled by a sink term in vapor equation in the numerical analysis for different geometries in wide range of cavitation numbers. The r...
متن کاملCavitating Vortex Flow Generated by a Stationary Volute Casing and a Rotating Centrifugal Impeller
Three devices for treating contaminated water using a cavitating vortex have been developed and tested. The first device uses stationary twin volute casings to generate cavitating vortices. Observation of the collisions among the opposing counter-rotating vortices revealed that their end portions whirl, that the vortices never collide head-on, and that they eventually separate into several smal...
متن کاملThe singing vortex.
Marine propellers display several forms of cavitation. Of these, propeller-tip vortex cavitation is one of the important factors in propeller design. The dynamic behaviour of the tip vortex is responsible for hull vibration and noise. Thus, cavitation in the vortices trailing from tips of propeller blades has been studied extensively. Under certain circumstances cavitating vortices have been ob...
