Available in PDF, EPUB and Kindle. Book excerpt: Previous investigations of oscillating (harmonic) flow past circular cylinders via the discrete vortex method have met with limited success due to a variety of reasons. These assumptions have proven to be too severe, and cannot allow the prediction of the kinematics and dynamics of the oscillating flow about bluff bodies in general and about a circular cylinder in particular. In the current analysis, the ambient velocity was given by U = Um sin wt, and the velocity distribution and the boundary layer were calculated about the cylinder at suitable time intervals. Several methods were implemented to predict separation, all of which required a minimum of arbitrary assumptions. Nascent vortices were placed at the separation points in such a manner that the Kutta condition was satisfied. Several functional forms of dissipation were investigated, but it was found not to be of overriding influence in the flow kinematics. Counter vortices were found to be a necessary aspect of the analysis, providing continuity from one half cycle to the next. Flow visualization experiments were conducted for a Keulegan-Carpenter number of 10 as a basis for comparison. The kinematics obtained from the numerical model produced a vortex shedding pattern which was typical of those observed experimentally for higher Keulegan-Carpenter numbers. Significant problems were encountered in the prediction of boundary layer separation. At this point, it was obvious that the interaction of a vortex with a boundary layer warranted analysis in a much simpler flow situation; the blade-vortex interaction (BVI) problem proved to be ideal.

Available in PDF, EPUB and Kindle. Book excerpt: In this contribution, we present a set of procedures developed to identify fluid flow structures and characterize their space-time evolution in time-dependent flows. In particular, we consider two different contests of importance in applied fluid mechanics: 1) large-scale almost 2D atmospheric and oceanic flows and 2) flow inside the left ventricle in the human blood circulation. For both cases, we designed an ad hoc experimental model to reproduce and deeply investigate the considered phenomena. We will focus on the post-processing of high-resolution velocity data sets obtained via laboratory experiments by measuring the flow field using a technique based on image analysis. We show how the proposed methodologies represent a valid tool suitable for extracting the main patterns and quantify fluid transport in complex flows from both Eulerian and Lagrangian perspectives.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Vortex Dominated Flows written by Lu Ting and published by Springer Science & Business Media. This book was released on 2007-07-05 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides in-depth analyses of vortex dominated flows via matched and multiscale asymptotics, and demonstrates how insight gained through these analyses can be exploited in the construction of robust, efficient, and accurate numerical techniques. The book explores the dynamics of slender vortex filaments in detail, including fundamental derivations, compressible core structure, weakly non-linear limit regimes, and associated numerical methods. Similarly, the volume covers asymptotic analysis and computational techniques for weakly compressible flows involving vortex-generated sound and thermoacoustics. The book is addressed to both graduate students and researchers.

Book Synopsis Vortex Flows and Related Numerical Methods by : J.T. Beale
Download or read book Vortex Flows and Related Numerical Methods written by J.T. Beale and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many important phenomena in fluid motion are evident in vortex flow, i.e., flows in which vortical structures are significant in determining the whole flow. This book, which consists of lectures given at a NATO ARW held in Grenoble (France) in June 1992, provides an up-to-date account of current research in the study of these phenomena by means of numerical methods and mathematical modelling. Such methods include Eulerian methods (finite difference, spectral and wavelet methods) as well as Lagrangian methods (contour dynamics, vortex methods) and are used to study such topics as 2- or 3-dimensional turbulence, vorticity generation by solid bodies, shear layers and vortex sheets, and vortex reconnection. For researchers and graduate students in computational fluid dynamics, numerical analysis, and applied mathematics.

Download or read book Modelling of Time-Variant Flows Using Vortex Dynamics written by ADVISORY GROUP FOR AEROSPACE RESEARCH AND DEVELOPMENT NEUILLY-SUR-SEINE (France) and published by . This book was released on 1987 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been a marked growth in the applications of vortex dynamics to time-varying flows, usually involving separated regions with vortical structures. The flow models are based on distributions of vortex elements which may vary in complexity. This report is a compilation of invited papers which cover current and projected developments in France, Germany, Greece, Italy, Netherlands, UK and USA. The report provides a good overall view of the 'state of the art' of the topic, covering both the achievements and the deficiencies requiring future research. The outstanding problems centre on how the effects of viscosity can be done to deal with the effects of compressibility. However, methods based on vortex dynamics seen particularly suited to problems involving well defined, large scale vortical flows which they provide a more direct physical insight into the nature of the flow than other methods. Keywords: Fluid dynamics; Viscous flow; Compressible flow; Mathematical models.

Book Synopsis Vortex Element Methods for Fluid Dynamic Analysis of Engineering Systems by : R. I. Lewis
Download or read book Vortex Element Methods for Fluid Dynamic Analysis of Engineering Systems written by R. I. Lewis and published by Cambridge University Press. This book was released on 2005-07-21 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Panel methods employing surface distributions of source and vortex singularities based on the solution of boundary integral equations have been extensively used for modeling external and internal aerodynamic flows. Part 1 describes the surface vorticity method and illustrates applications of this technique over a wide range of engineering problems in aerodynamics and turbomachines, including lifting aerofoils and cascades, mixed-flow and rotating cascades for fans, pumps or turbines, meridional flows in turbomachines, flow past axisymmetric bodies, ducts and ducted propellers or fans. Part 2 extends surface vorticity modeling to the fairly new CFM field of vortex dynamics or vortex cloud theory. Methods are developed, again from first principles, to deal with shear layers, boundary layers, periodic wakes, bluff-body flows, cascades and aerofoils including the use of stall control spoilers. A number of useful computer programs are included.
Book Synopsis Vortex Methods by : Georges-Henri Cottet
Download or read book Vortex Methods written by Georges-Henri Cottet and published by Cambridge University Press. This book was released on 2008-04-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vortex methods have matured in recent years, offering an interesting alternative to finite difference and spectral methods for high resolution numerical solutions of the Navier Stokes equations. In the past three decades, research into the numerical analysis aspects of vortex methods has provided a solid mathematical background for understanding the accuracy and stability of the method. At the same time vortex methods retain their appealing physical character, which was the motivation for their introduction. This book presents and analyzes vortex methods as a tool for the direct numerical simulation of impressible viscous flows. It will interest graduate students and researchers in numerical analysis and fluid mechanics and also serve as an ideal textbook for courses in fluid dynamics.
