Book excerpt: Abstract: Flow visualization has been playing a substantial role in many engineering and scientific applications, such as automotive industry, computational fluid dynamics, chemical processing, and weather simulation and climate modelling. Many methods have been proposed in the past decade to visualize steady and time-varying flow fields, in which textures-based and geometry-based visualization are widely used to explore the underlying fluid dynamics. This dissertation presents a view-dependent flow texture algorithm, an illustrative streamline placement algorithm on two-dimensional vector fields, and an image-based streamline placement algorithm on three-dimensional vector fields. Flow texture, generated through convolution and filtering of texture values according to the local flow vectors, is a dense representation of the vector field to provide global information of the flow structure. A view-dependent algorithm for multi-resolution flow texture advection on two-dimensional structured rectilinear and curvilinear grid is presented. By using an intermediate representation of the underlying flow fields, the algorithm can adjust the resolutions of the output texture on the fly as the user zooms in and out of the field, which can avoid aliasing as well as ensure enough detail. Geometry-based methods use geometries, such as lines, tubes, or balls, to represent the motion paths advected from the vector fields. It provides a sparse representation and an intuitive visualization of flow trajectory. For two-dimensional vector fields, a streamline placement strategy is presented to generate representative and illustrative streamlines, which can effectively prevent the visual overload by emphasizing the essential and deemphasizing the trivial or repetitive flow patterns. A user study is performed to quantify the effectiveness of this visualization algorithm, and the results are provided. For three-dimensional vector fields, an image-based streamline seeding algorithm is introduced to better display the streamlines and reduce visual cluttering in the output images. Various effects can be achieved to enhance the visual understanding of three-dimensional flow lines.

This book was released on 2012-12-06 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in fluid mechanics depends heavily on the availability of good experimental data which can inspire new ideas and concepts but which are also necessary to check and validate theories and numerical calculations. With the advent of new recording and image analysis techniques new and promising experimental methods in fluid flows have presented themselves which are rather newly developed techniques such as particle tracking velocimetry (PTV), particle image velocimetry (PIV) and laser fluorescene (LIF). This volume presents state-of-the-art research on these techniques and their application to fluid flow. Selected papers from the EUROMECH conference on Image Analysis are published in this volume.

Book excerpt: This is the 2nd edition of the book, Flow Visualization: Techniques and Examples, which was published by Imperial College Press in 2000. Many of the chapters have been revised and updated to take into consideration recent changes in a number of flow visualization and measurement techniques, including an updated high quality flow gallery. Unique among similar publications, this book focuses on the practical rather than theoretical aspects. Obtaining high quality flow visualization results is, in many ways, more of an art than a science, and experience plays a key deciding role. The depth and breadth of the material will make this book invaluable to readers of all levels of experience in the field.

Download or read book Visualized Flow written by Yasuki Nakayama and published by . This book was released on 1988 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow Visualization always plays an important role in understanding flow phenomena and contributes significantly to the physical intuitive reasonong necessary to successfully apply the knowledge gained to real life situations. This book is designed to enhance the understanding of basic flow phenomena through over 200 high quality flow visualization photographs, some in colour, and explanations. The book opens with a summary of flow visualization methods, and then proceeds to present flow phenomena as revealed by various flow visualization techniques. The treatment ranges from fundamental aspects, such as laminar and turbulent flow, to engineering applications; for example, understanding why cavitation damage occurred on the runner of a Francis turbine. Current and new visualization techniques are employed such that invisible flow, as in air and water, is made clearly visible and comprehensible. Visualized Flow was compiled and edited under the guidance of the Japanese Society of Mechanical Engineers. This English edition will be indispensable to engineers, researchers and students in understanding flow phenomena across the wide range of sciences wherever fluid flow is important.

Available in PDF, EPUB and Kindle. Book excerpt: Within both the scientific and academic communities, the study and visualization of flow is an essential tool used to model fluid transport and mixing. Modern Computational Fluid Dynamics (CFD) simulations are used to successfully approximate real-world physics to reproduce dynamic flow behavior, however, from simulation to visualization, maintaining a high level of accuracy is fraught with obstacles. In this thesis, we address two major challenges to visualizing fluid flow data accurately. The first challenge, encountered during the simulation stage, is the inability of supercomputers to allow simulations to be saved at their native resolution. The second challenge, confronted in the post-processing stage, involves combating the substantial and discouraging computational expense associated with highly accurate particle-based visualization techniques. We begin by presenting a framework for detecting and accumulating flow characteristics during the particle advection process, aimed at optimizing the associated computational burden. Consequently, we provide evidence of a wealth of fluid flow knowledge that can be gained with little computational overhead. We then extend the detection of these flow transformation effects to the simulation stage, offering a novel compression algorithm designed to dynamically distribute the constrained budget set when writing simulation results to disk. The output focuses on flow deformation and rotation, thereby improving visualization accuracy in turbulent regions. Next, we describe the versatility of interpolation as a substitute for costly and iterative numerical integration. We present a method for categorizing salient flow features using only a sub- set of advected particles to interpolate the remaining domain information. Overall, the number of advection steps is drastically cut down and our method is able to better visualize features of interest with fewer particles. Building on this work, we eliminate advection entirely and develop an inter- active exploration environment based solely on interpolating trajectory position information. After achieving positive results in the visualization stage, we further explore the Lagrangian representation - a dense sampling of the flow field with particle trajectories - as an alternative output to CFD simulations. Through a series of comprehensive tests, we verify that the Lagrangian representation is less sensitive than traditional output to the unavoidable temporal compression that occurs when writing to disk. Subsequently, we demonstrate that particle trajectories extracted during the post- processing stage are more accurate, with the added benefit of increased performance and less disk space usage necessary to store the simulation output itself. The primary objective of our work is to advance the field of flow visualization, focusing on the challenges that arise when high accuracy is required. With CFD simulations growing ever more complex and many scientists within academia and industry turning to flow visualization, we provide solutions to help retain flow field accuracy while optimizing both the storage of simulation data on disk and the computational expense of particle-based visualization techniques.

Book excerpt: Water and air produce many kinds of flow. For example, the flow in a stream, the wind around a towerblock and the turbulence around an airplane. This book was edited with two goals; one is to show the very close relationship between fluid flow and our life and the other is to introduce the form and beauty of fluid flow. Recently, great progress has been made in flow visualization techniques. As the proverb says 'Seeing is believing', seeing is the best way to understand the phenomena of flow. The full color pictures of this book will initiate the readers' interest in the beauty of flow and encourage them to discover more about the fluid flow around themselves.
