he Effect of a Longitudinal Gravitational Field on the Super - cavitating Flow Over a Wedge

چکیده
IN recent years a number of papers treating linearized free-streamline problems have appeared subsequent to Tulin's introductory paper on this subject [1] .1 Among these may be mentioned Wu's extension of Tulin's method for supercavitating hydrofoils with arbitrary shape and cavitation number [2], hydrofoils with cavitation only near the leading edge. [3], supercavitating hydrofoils in cascade [4], and Cohen's work on wall-interference effects [5]. In all of these works the hydrofoil is assumed to be in a force-free field. However, Parkin recently has estimated the effect of a gravity field normal to the direction of the flow by means of a simplified representation of the gravity effect on the cavity boundary condition [6]. As yet the problem of the longitudinal gravity field does not seem to have been discussed.

Influence of Afterbody and Boundary Layer on Cavitating Flow
The characteristics of a cavitation water tunnel test setup and the experiments of cavitation around different models are given in this paper. Models of test are formed from combination of head and variable length afterbody. The experiments are performed initially with the smooth head and then with the roughened head. Cavitation initiates both in the wake and after the head. If the nose of mode...
متن کاملA Novel Indicator to Predict the Onset of Instability of a Gravitational Flow on a Slope
In order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. These points are obtained by means of the solution of the two-dimensional Navier-Stokes equations via the standard Arakawa-C finite-difference method. Results show that in the marginal Richardson numbers, the critical...

متن کاملPhysical Modelling of Self-Aeration in a Cavitating Sudden PIPE Expansion Flow
Sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. The complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. This paper focuses on aeration in sudden pipe expans...
