Book Description
Measurements of the boundary-layer characteristics and pressure distribution on three axisymmetric bodies with and without a propeller in operation are correlated with analytical techniques for computing (1) the interaction between the hull boundary layer flow and the potential flow and (2) the interaction between the operating propeller and the thick stern boundary layer. The agreement between the measured and computed shear stresses, pressure distributions, and velocity profiles was satisfactory except over the last 5 percent of body length on the two fullest afterbodies. An inviscid propeller-stern-boundary-layer interaaction model was developed and found to give accurate predictions of effective velocity profiles. The experimental results show that the potential-flow propeller-hull interaction methods give accurate predictions for thrust deduction and the propeller-induced pressure distribution. The present analytical techniques will be useful for predicting the full-scale effective velocity profile for propeller design when account is taken of the effects of Reynolds number, roughness, and propeller suction in modifying the nominal velocity profiles.

Pages : 19
Book Description
A computer program which calculates the inviscid approximation of propeller/stern boundary-layer interaction is given. The description includes a summary of the inviscid theory and the assumptions used, an outline of the numerical procedure and computation method, a numerical example, FORTRAN listing, and input and output instructions. This program is designed to compute the effective velocity profile from the measured nominal velocity profile for propeller design. (Author).

Twenty-Third Symposium on Naval Hydrodynamics
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309254671
Category : Science
Languages : en
Pages : 1024
Book Description
"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.
