Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the development of a three-dimensional time-domain numerical model for calculating hull pressures as well for as hydroelastic analysis of a ship hull in waves. In this work, hydrodynamic forces & pressures due to radiated & diffracted waves are expressed as convolution products of a response function with either the velocity of ship motion or the wave elevation. The method significantly reduces the need for numerical evaluation of the time-domain Green function in the convolution of memory effects. The response functions of forces & pressures of radiated & diffracted waves are obtained by numerically solving the Fredholm integral equation of the first kind. In the equations of motion, maneuvering & rudder forces, radiation & diffraction forces, and non-linear restoring & Froude-Krylov forces are taken into account. Numerical examples are presented to compare computed & measured results.

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Ship Hydrodynamics: Fluid Mechanics, Ship Resistance and Propulsion Lothar Birk, University of New Orleans, USA Bridging the information gap between fluid mechanics and ship hydrodynamics Fundamentals of Ship Hydrodynamics is designed as a textbook for undergraduate education in ship resistance and propulsion. The book provides connections between basic training in calculus and fluid mechanics and the application of hydrodynamics in daily ship design practice. Based on a foundation in fluid mechanics, the origin, use, and limitations of experimental and computational procedures for resistance and propulsion estimates are explained. The book is subdivided into sixty chapters, providing background material for individual lectures. The unabridged treatment of equations and the extensive use of figures and examples enable students to study details at their own pace. Key features: • Covers the range from basic fluid mechanics to applied ship hydrodynamics. • Subdivided into 60 succinct chapters. • In-depth coverage of material enables self-study. • Around 250 figures and tables. Fundamentals of Ship Hydrodynamics is essential reading for students and staff of naval architecture, ocean engineering, and applied physics. The book is also useful for practicing naval architects and engineers who wish to brush up on the basics, prepare for a licensing exam, or expand their knowledge.

Download or read book Time-Domain Method for Computing Forces and Moments Acting on Three Dimensional Surface-Piercing Ship Hulls with Forward Speed written by Richard B. Chapman and published by . This book was released on 1980 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A time-domain simulation method for computing forces and moments acting on an arbitrary surface-piercing three-dimensional ship hull is presented. Arbitrary motions can be prescribed and are assumed to be sufficiently small so that the linearized method is valid. Forward speed effects are included under the assumption that the disturbance generated by forward motion is also small and interactions with the flow generated by the prescribed motions are of second order. The hull is represented by a set of quadrilateral surface panels in a body-fixed system, while the free surface is represented by its spectral coordinates in a space-fixed rectangular system. Small time steps are used to advance the flow. This time-domain computation can also be applied to compute linearized seakeeping responses in the frequency domain. For each degree of freedom, a unit step function is applied to the velocity. The resulting impulsive forces and moments and the computed time histories of these forces and moments after the step in velocity can then be combined to compute the added mass and damping forces and moments in the frequency domain. Wave-excited forces can be computed by similar method. As a check on the computer program, the added mass and damping of a semi-submerged sphere oscillating in heave were computed numerically. The results show good agreement with analytic mass and damping coefficients for a fairly coarse representation of the hull and free surface. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In the spring of 1971, Reinier Tirnrnan visited the University of Delaware during which time he gave a series of lectures on water waves from which these notes grew. Those of us privi leged to be present during that time will never forget the experience. Rein Tirnrnan is not easily forgotten. His seemingly inexhaustible energy completely overwhelmed us. Who could forget the numbing effect of a succession of long wine filled evenings of lively conversation on literature, politics, education, you name it, followed early the next day by the appearance of the apparently totally refreshed red haired giant eager to discuss our mathematical problems with keen insight en remarkable understanding, ready to lecture on fluid mechanics or optimal control theory or a host of other subjects and ready to work into the evening until the cycle repeated. He thought faster, he knew more, he drank more and he slept less than any of us mortals and he literally wore us out. What a rare privilege indeed to have participated in this intellectual orgy. Tirnrnan's lively interest in almost every thing coupled with his buoyant enthusiasm and infectious op timism epitomized his approach to life. No delicate nibbling at the fringes, he wanted every morsel of every course. In these times of narrow specialization truly renaissance figures are, if not extinct, at least a highly endangered species. But Tirnrnan was one of that rare breed.
