This book was released on 1990 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from experiments designed to study the sound from different types of propeller cavitation. The propellers used in the tests produced tip vortex and travelling bubble cavitation. The spectral content, directivity, and waveform of the far-field sound were measured, in essentially free-field conditions up to 100 kHz. These data were then correlated with information about the cavity dynamics, obtained from visual observations. Vibrational modes on the tip vortex cavities produced sound at characteristic frequencies. Bubble cavitation by itself produced very broadband noise, and strongly affected the vortex cavitation noise mechanisms if the free bubbles entered the tip vortices. The noise from both kinds of cavitation was directional. Keywords: Propeller, Cavitation, Noise, Spectra, Directivity, Waveform, Canada. (JHD).

Available in PDF, EPUB and Kindle. Book excerpt: Measurements made long ago of the underwater noise associated with propeller tip-vortex cavitation on a submerged WWII submarine underway at sea, combined with measurements of the noise from a geometrically scaled model of the same submarine running submerged and self propelled in our towing basin, are used to calculate the value of the exponent in McCormick's equation, (sigma (sub rho)/sigma (sub MU))=(Re(sub rho)/Re(sub MU))(exp n), relating the ratio of full-scale to model cavitations numbers at cavitation inception to the ratio of the Reynolds numbers. The value of n is calculated to be 0.28, which is smaller than the usually assumed values ranging from 0.3 to 0.4. This provides evidence that n is not a constant, but decreases with increasing Reynolds number.

Book excerpt: "Vive la Revolution!" was the theme of the Twenty-Third Symposium on Naval Hydrodynamics held in Val de Reuil, France, from September 17-22, 2000 as more than 140 experts in ship design, construction, and operation came together to exchange naval research developments. The forum encouraged both formal and informal discussion of presented papers, and the occasion provides an opportunity for direct communication between international peers. This book includes sixty-three papers presented at the symposium which was organized jointly by the Office of Naval Research, the National Research Council (Naval Studies Board), and the Bassin d'Essais des Carènes. This book includes the ten topical areas discussed at the symposium: wave-induced motions and loads, hydrodynamics in ship design, propulsor hydrodynamics and hydroacoustics, CFD validation, viscous ship hydrodynamics, cavitation and bubbly flow, wave hydrodynamics, wake dynamics, shallow water hydrodynamics, and fluid dynamics in the naval context.
