Opis

Knowledge of added body masses that interact with fluid is necessary in various research and applied tasks of hydro- and aeromechanics: steady and unsteady motion of rigid bodies, total vibration of bodies in fluid, local vibration of the external plating of different structures. This reference book contains data on added masses of ships and various ship and marine engineering structures. Also theoretical and experimental methods for determining added masses of these objects are described. A major part of the material is presented in the format of final formulas and plots which are ready for practical use. The book summarises all key material that was published in both Russian and English-language literature. This volume is intended for technical specialists of shipbuilding and related industries. The author is one of the leading Russian experts in the area of ship hydrodynamics.

Recenzje

"This book impresses by its width and completeness, as well as by consistency of presentation; it is going to be extremely useful in our work." (Nekrasov V.A., Professor, Chair of Departments of ship theory, Nikolaev State University, Ukraine)

"One should stress that this reference book can be used not only in ship engineering, but also in aviation engineering, hydrotechnique, machine engineering, i.e. everywhere where one deals with interaction of constructions with fluid." (editorial, Morskoj Vestnik, No. 1 (25), p.105, 2008)

"In applied problems of design of engineering objects, interacting with a liquid medium, added masses determine the forces and moments acting on the constructions, especially in non-stationary regimes of motion. The book of Professor Korotkin, in which the majority of existing data on added masses of various bodies is collected, will take a reputable position in reference literature on hydromechanics." (Kirill V. Rozhdestvenskij, Vice-Chancellor and Head of the Department of Applied Mathematics and Mathematical Modeling of St. Petersburg State Maritime Technical University)

"This book is unique. It will undoubtedly be called for by designers of ships and of other engineering structures interacting with fluids. For these specialists the reference book will certainly become an indispensable source of information. The book is encyclopedic because the author has combined a wide range of diverse issues related to the determination of added masses: analytical and numerical methods of calculation, approximate computation methods, experimental techniques.
Book materials are presented in the form of final formulas, graphs and tables, handy for practical application." (Aron S. Ginevskij, professor, Central Aerohydrodynamic Institute, Moscow, Russia)

"In various problems of hydrodynamics of ships, vessels and conversion aids of the World Ocean, an important role is played by researching of non-stationary movements of objects. Information about added masses of various structures is a key element in the process of solving these problems. The book by Professor A. I. Korotkin "Added masses of ship structures" is a reference book of high quality, based on many years of experience of the author and experts of Krylov Shipbuilding Research Institute." (Alexander V. Pustoshnyi, Corresponding member of the Russian Academy of Sciences, Member of the National Committee on "Mechanics" of the Russian Academy of Sciences, Head of Department and Deputy Director of Krylov Shipbuilding Research Institute, St.Petersburg, Russia)
