Available in PDF, EPUB and Kindle. Book excerpt: Despite their variety, the vibration phenomena from many different engineering fields can be classified into a relatively few basic excitation mechanisms. The classification enables engineers to identify all possible sources of excitation in a given system and to assess potential dangers. This graduate-level text presents a synthesis of research results and practical experience from disparate fields in the form of engineering guidelines. It is particularly geared toward assessing the possible sources of excitation in a flow system, in identifying the actual danger spots, and in finding appropriate remedial measures or cures. Flow-induced vibrations are presented in terms of their basic elements: body oscillators, fluid oscillators, and sources of excitation. By stressing these basic elements, the authors provide a basis for the transfer of knowledge from one system to another, as well as from one engineering field to another. In this manner, well-known theories on cylinders in cross-flow or well-executed solutions from the field of wind engineering--to name just two examples--may be useful in other systems or fields on which information is scarce. The unified approach is broad enough to permit treatment of the major excitation mechanism, yet simple enough to be of practical use.

Available in PDF, EPUB and Kindle. Book excerpt: This is a concise and comprehensive review of the progress made during the past two decades on vortex induced vibration (VIV) of mostly circular cylindrical structures subjected to steady uniform flow. The critical elements of the evolution of the ideas, theoretical insights, experimental methods, and numerical models are traced systematically; the strengths and weaknesses of the current state of the understanding of the complex fluid/structure interaction are discussed in some detail. Finally, some suggestions are made for further research on VIV. The organization of the paper is given at the end of the next section.

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, we use controlled vibration, where we oscillate a rigid cylinder with a prescribed motion, in a fluid flow, in order to provide insight into aspects of vortex-induced vibration. We make extensive measurements of the fluid forces on a cylinder that oscillates sinusoidally, transverse to a free stream, at both Re = 4,000 and Re = 12,000, and generate high resolution contour plots of various fluid forcing quantities in the plane of normalized amplitude and wavelength. With such resolution, we are able to discover discontinuities in the force and phase contours, which enable us to clearly identify boundaries separating different fluid forcing regimes. These boundaries appear remarkably similar to boundaries separating different vortex formation modes in the Williamson & Roshko (1988) map of regimes. Wake vorticity measurements (using DPIV) exhibit the 2S, 2P, and P+S modes, as well as a regime where the vortex formation is not synchronized with the cylinder oscillation. A further new discovery is the existence of a region where two vortex formation regimes overlap. Associated with this overlap region, we identify a distinct mode of vortex formation where two pairs of vortices are shed per cycle of oscillation (similar to the 2P mode) but the secondary vortex is much weaker, which we have termed '2POVERLAP ', or simply the '2PO ' mode. This '2PO ' mode is of particular importance, as it is responsible for generating the peak resonant response of the body. By examining the energy transfer from fluid to body motion we predict the response of an elastically mounted cylinder that agrees remarkably well with measured free vibration responses. We introduce the concept of an "energy portrait", which allows us to identify stable and unstable amplitude response solutions and thus to predict clearly the hysteretic and intermittent switching mode transitions, both of which correspond with such phenomena measured from free vibration. In addition to predicting steady state (sinusoidal) behavior, we develop a quasi-steady model which allows us to predict the dynamics of a freely oscillating cylinder having transient or unsteady behavior. Using this model, we find a regime of normalized flow velocity where steady state vortex-induced vibrations cannot occur, and the cylinder can only oscillate with unsteady motion. Further studies include the effect of Reynolds number on the critical mass for an oscillating body, below which a structure will vibrate up to infinite normalized velocity. Finally, we measure the effect of spanwise end conditions on a free vibration response.

Download or read book Hydrodynamics Around Cylindrical Structures written by Jorgen Fredsoe and published by World Scientific. This book was released on 1997-03-17 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the subject of wave/current flow around a cylinder, the forces induced on the cylinder by the flow, and the vibration pattern of slender structures in a marine environment.The primary aim of the book is to describe the flow pattern and the resulting load which develops when waves or current meet a cylinder. Attention is paid to the special case of a circular cylinder. The development in the forces is related to the various flow patterns and is discussed in detail. Regular as well as irregular waves are considered, and special cases like wall proximities (pipelines) are also investigated.The book is intended for MSc students with some experience in basic fluid mechanics and for PhD students.
