Added Masses of Ship Structures

Abstract

Aims and Scope of the SeriesThe purpose of this series is to focus on subjects in which fluid mechanics plays a fundamental role.As well as the more traditional applications of aeronautics, hydraulics, heat and mass transfer etc., books will be published dealing with topics which are currently in a state of rapid development, such as turbulence, suspensions and multiphase fluids, super and hypersonic flows and numerical modeling techniques.It is a widely held view that it is the interdisciplinary subjects that will receive intense scientific attention, bringing them to the forefront of technological advancement. Fluids have the ability to transport matter and its properties as well as to transmit force, therefore fluid mechanics is a subject that is particularly open to cross fertilization with other sciences and disciplines of engineering. The subject of fluid mechanics will be highly relevant in domains such as chemical, metallurgical, biological and ecological engineering. This series is particularly open to such new multidisciplinary domains.The median level of presentation is the first year graduate student. Some texts are monographs defining the current state of a field; others are accessible to final year undergraduates; but essentially the emphasis is on readability and clarity.For other titles published in this series, go to This is an updated and revised translation of the original Russian work entitled «Присоединенные массы судостроительных конструкции», by A. Korotkin, Morwest, St. Petersburg, Russia, 2007.

Experiments on the water entry of curved wedges: High speed imaging and particle image velocimetry

“…One of the seminal studies in this field is attributed to Von Karman (1929), who formulated an approximate scheme to predict the impact dynamics of a flat wedge. Since then, many authors have extended Von Karman's solution to describe water pile-up in the vicinity of the wedge and its effect on the added mass (Wagner, 1932;Chuang, 1996;Payne, 1995;Wu, 1998;Pesce, 2003;Korotkin, 2009). Central to most of these approaches is the pile-up coefficient, which quantifies the ratio between the horizontal projection of the wetted surface of the wedge and its projected surface with respect to the initial water surface.…”

Dynamic behavior of a second generation hydrokinetic converter

“…That is why it was decided to do a more detailed study of the hydrodynamic behaviour (drag and added mass) [23,24], of the generator structure and make some tests in a towing tank, with the model of Fig. 10, that will be finished in few months.…”

The eyeball ROV: Design and control of a spherical underwater vehicle steered by an internal eccentric mass

“…These additional hydrodynamic matrices are defined below. Note that for a spherical body all added mass terms are equal to 50% of the mass of the fluid displaced by the body [6], [7].…”

“…[ ] ( ) c is the lift coefficient [7], [8]. With these hydrodynamic effects considered, the dynamics become:…”
