Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive study was performed of hydrodynamic forces and moments on submarine hull geometries with casings in steady translation using an enhanced database consisting of experimental and computational results. The objective was to develop a hydrodynamic load estimation method that allows for the rapid simulation of the performance characteristics of underwater vehicles. This is an important step in determining the safe operating envelope of submarines. Accurate potential flow and viscous flow results of the geometries of interest were performed at varying incidence and orientation angles. The simulations were verified by a mesh refinement study and validated against analytical solutions and experimental data. Potential flow was found to be a useful predictor of the effects of geometric asymmetric on the out-of-plane and in-plane force distributions and moments. The viscous simulations showed that casings, and hull asymmetries in general, have significant effects on the separation lines, surface pressure distributions, and wake topologies. These effects caused large variations in the in-plane loads and introduced out-of-plane loads. Increasing the casing width produced the largest changes in the in-plane and out-of-plane loads and wake topology. Previous models were found to be unsuitable for the prediction of the in-plane loads on hulls with casings mainly due to their reliance on slender body theory. An alternative model was developed, which combined potential flow with viscous contributions to obtain the hydrodynamic impulse. The tail plane impulse, and therefore the hydrodynamic force, could be approximated with the first nine Fourier modes of the orientation angle. The hydrodynamic moment predictions were found to be accurate. The model was found to have difficulty in predicting the in-plane moment for small asymmetries such as a narrow casing.

This book was released on 2000-03-02 with total page 1039 pages. Available in PDF, EPUB and Kindle. 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 Marine Hydrodynamics 40th anniversary edition written by J. N. Newman and published by MIT Press. This book was released on 2018-01-26 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: A textbook that offers a unified treatment of the applications of hydrodynamics to marine problems. The applications of hydrodynamics to naval architecture and marine engineering expanded dramatically in the 1960s and 1970s. This classic textbook, originally published in 1977, filled the need for a single volume on the applications of hydrodynamics to marine problems. The book is solidly based on fundamentals, but it also guides the student to an understanding of engineering applications through its consideration of realistic configurations. The book takes a balanced approach between theory and empirics, providing the necessary theoretical background for an intelligent evaluation and application of empirical procedures. It also serves as an introduction to more specialized research methods. It unifies the seemingly diverse problems of marine hydrodynamics by examining them not as separate problems but as related applications of the general field of hydrodynamics. The book evolved from a first-year graduate course in MIT's Department of Ocean Engineering. A knowledge of advanced calculus is assumed. Students will find a previous introductory course in fluid dynamics helpful, but the book presents the necessary fundamentals in a self-contained manner. The 40th anniversary of this pioneering book offers a foreword by John Grue. Contents Model Testing • The Motion of a Viscous Fluid • The Motion of an Ideal Fluid • Lifting Surfaces • Waves and Wave Effects • Hydrodynamics of Slender Bodies
Download or read book Particles in Flows written by Tomáš Bodnár and published by Birkhäuser. This book was released on 2017-09-30 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to face particles in flows from many different, but essentially interconnected sides and points of view. Thus the selection of authors and topics represented in the chapters, ranges from deep mathematical analysis of the associated models, through the techniques of their numerical solution, towards real applications and physical implications. The scope and structure of the book as well as the selection of authors was motivated by the very successful summer course and workshop "Particles in Flows'' that was held in Prague in the August of 2014. This meeting revealed the need for a book dealing with this specific and challenging multidisciplinary subject, i.e. particles in industrial, environmental and biomedical flows and the combination of fluid mechanics, solid body mechanics with various aspects of specific applications.

This book was released on 2016-09-26 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: With this self-contained and comprehensive text, students and researchers will gain a detailed understanding of the fundamental aspects of the hydrodynamic control of wave energy converters. Such control is necessary to maximise energy capture for a given device configuration and plays a major role in efforts to make wave energy economic. Covering a wide range of disciplines, the reader is taken from the mathematical and technical fundamentals, through the main pillars of wave energy hydrodynamic control, right through to state-of-the-art algorithms for hydrodynamic control. The various operating principles of wave energy converters are exposed and the unique aspects of the hydrodynamic control problem highlighted, with a variety of potential solutions discussed. Supporting material on wave forecasting and the interaction of the hydrodynamic control problem with other aspects of wave energy device optimisation, such as device geometry optimisation and optimal device array layout, is also provided.
Download or read book Flight Vehicle Aerodynamics written by Mark Drela and published by MIT Press. This book was released on 2014-02-07 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the physics, concepts, theories, and models underlying the discipline of aerodynamics. This book offers a general overview of the physics, concepts, theories, and models underlying the discipline of aerodynamics. A particular focus is the technique of velocity field representation and modeling via source and vorticity fields and via their sheet, filament, or point-singularity idealizations. These models provide an intuitive feel for aerodynamic flow-field behavior and are the basis of aerodynamic force analysis, drag decomposition, flow interference estimation, and other important applications. The models are applied to both low speed and high speed flows. Viscous flows are also covered, with a focus on understanding boundary layer behavior and its influence on aerodynamic flows. The book covers some topics in depth while offering introductions and summaries of others. Computational methods are indispensable for the practicing aerodynamicist, and the book covers several computational methods in detail, with a focus on vortex lattice and panel methods. The goal is to improve understanding of the physical models that underlie such methods. The book also covers the aerodynamic models that describe the forces and moments on maneuvering aircraft, and provides a good introduction to the concepts and methods used in flight dynamics. It also offers an introduction to unsteady flows and to the subject of wind tunnel measurements. The book is based on the MIT graduate-level course “Flight Vehicle Aerodynamics” and has been developed for use not only in conventional classrooms but also in a massive open online course (or MOOC) offered on the pioneering MOOC platform edX. It will also serve as a valuable reference for professionals in the field. The text assumes that the reader is well versed in basic physics and vector calculus, has had some exposure to basic fluid dynamics and aerodynamics, and is somewhat familiar with aerodynamics and aeronautics terminology.
