Book excerpt: The Twenty-Second Symposium on Naval Hydrodynamics was held in Washington, D.C., from August 9-14, 1998. It coincided with the 100th anniversary of the David Taylor Model Basin. This international symposium was organized jointly by the Office of Naval Research (Mechanics and Energy Conversion S&T Division), the National Research Council (Naval Studies Board), and the Naval Surface Warfare Center, Carderock Division (David Taylor Model Basin). This biennial symposium promotes the technical exchange of naval research developments of common interest to all the countries of the world. The forum encourages both formal and informal discussion of the presented papers, and the occasion provides an opportunity for direct communication between international peers.
Download or read book Numerical Methods for Seakeeping Problems written by Bettar Ould el Moctar and published by Springer Nature. This book was released on 2021-01-19 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes currently applied and newly developed advanced numerical methods for wave-induced ship motions and loads. Besides well-established computational methods based on strip theory, panel methods and finite volume methods for unsteady Reynolds-averaged Navier-Stokes equations (URANS), recent advances like a fully nonlinear Rankine panel method, URANS calculations including elastic hull deformations, and an improved method to predict added resistance in waves are explained in detail. Furthermore, statistical methods to assess extreme motions and loads are described both for linear and nonlinear responses in a stationary seaway as well as during long-term ship operations. Results of motions and loads, computed using the various methods, are compared with each other and with results of model experiments. Introductory chapters on fluid dynamics, motions of rigid and elastic ship hulls, numerical methods to compute fluid flows associated with wind waves, and the development and simulation of seaways complement the volume. The book will be of interest to post-graduate students, PhD candidates, as well as engineers in the field of naval architecture, ocean, and marine engineering.

This book was released on 1972 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical method for the determination of conventional merchant ship motions and wave-induced moments in a seaway is developed. Both vertical and lateral plane motions and loads are considered for a ship travelling at any heading in regular waves and in irregular long or short crested seas. Strip Theory is used in vertical, lateral and rolling oscillation modes. The coupled equations of motion are linear, and the superposition principle is used for statistical response calculations in irregular seas. All three primary ship hull loadings are determined, i.e. vertical bending, lateral bending and torsional moments, as well as shear forces, at any point along the length, with these responses only representing the low frequency slowly varying wave loads directly induced by the waves.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a numerical program has been developed to simulate the wave-induced ship motions in the time domain. Wave-body interactions have been studied for various ships and floating bodies through forced motion and free motion simulations in a wide range of wave frequencies. A three-dimensional Rankine panel method is applied to solve the boundary value problem for the wave-body interactions. The velocity potentials and normal velocities on the boundaries are obtained in the time domain by solving the mixed boundary integral equations in relation to the source and dipole distributions. The hydrodynamic forces are calculated by the integration of the instantaneous hydrodynamic pressures over the body surface. The equations of ship motion are solved simultaneously with the boundary value problem for each time step. The wave elevation is computed by applying the linear free surface conditions. A numerical damping zone is adopted to absorb the outgoing waves in order to satisfy the radiation condition for the truncated free surface. A numerical filter is applied on the free surface for the smoothing of the wave elevation. Good convergence has been reached for both forced motion simulations and free motion simulations. The computed added-mass and damping coefficients, wave exciting forces, and motion responses for ships and floating bodies are in good agreement with the numerical results from other programs and experimental data.

This book was released on 1979 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a follow-on project to SSC-240, 'Load Criteria for Ship Stuctural Design', which proposed methods for the estimation and superposition of the primary loads and performed sample calculations for one conventional dry cargo ship. It involved the following bending moments: still-water due to weight and buoyancy; ships own wave train; quasi-static wave-induced, vertical and lateral combined; dynamic loads, including slamming, whipping and springings; and thermal effects. Here the service and full-scale stress data of three larger and/or faster ships (Containership SL-7, Bulk Carrier FOTINI-L and very large Crude Carrier UNIVERSE IRELAND) are examined for the purpose of the enventual development of hull-girder criteria. The examination is limited to extreme midship bending moment loads which are related to the ultimate strength. An assessment is made of the compatibility between the service and stress data of the distinctly different study ships and the analysis methods of SSC-240 and their assumptions for cargo ship type. Considerable insight is obtained into the probable correct mathematical approximations of the loads and their interrelationships. It appears that still-water bending moments can be approached probabilistically, however, considerable additional information on experienced loading conditions must be gathered to determine the statistical distributions. Additional effort is required to determine the suitable probabilistic expression and a synthesis method for the contribution of vibration to the extreme load. (Author).
