Optical Methods for Data Processing in Heat and Fluid Flow
Author: Clive GreatedPublisher: John Wiley & Sons
ISBN: 9781860582813
Category : Science
Languages : en
Pages : 328
Book Description
Optical methods are now used routinely for the measurement of velocity, concentration, temperature, and other parameters in wide-ranging areas of industrial research and design such as IC engines, turbines, and combustors. Recent advances such as the use of high-resolution CCD cameras and the extension of flow mapping to three dimensions, make optical tools such as particle image velocimetry increasingly viable for use in the industrial environment. This excellent book presents new developments in optical diagnostic techniques in heat and fluid flow and offers an unparalleled opportunity for industrialists and academic researchers to exchange ideas. CONTENTS INCLUDE: Comparison of injector sprays for gasoline direct-injection engines The design, development, and preliminary results from a high-speed, optically accessed, single cylinder engine The reflected spectrum of complex multi-layered inhomogeneous highly scattering medium Development of full volume digital holography for particle measurement Improved liquid crystal thermography by using true-colour image processing technology Development of an optical measuring technique for the study of acoustical phenomena Spatio-temporal reconstruction of the unsteady wake of axisymmetric bluff bodies via time-recording DPIV Application of particle image velocimetry to helicopter vortex interactions Pulsed laser particle image velocimetry using a fibre-optic delivery system Automated fringe analysis for profilometric mass-transfer experiments.

Speckle Photography for Fluid Mechanics Measurements
Author: Nikita A. FominPublisher: Springer Science & Business Media
ISBN: 3662037076
Category : Technology & Engineering
Languages : en
Pages : 253
Book Description
Speckle photography is an advanced experimental technique used for quantitatve determination of density, velocity and temperature fields in gas, liquid, and plasma flows. This book presents the most important equations for the diffraction theory of speckle formation and the statistical properties of speckle fields. It also describes experimental set-ups and the equipment needed to implement these methods. Speckle photography methods for automatic data acquisition and processing are considered and examples for their use are given.
Flow Visualization
Author: A J SmitsPublisher: World Scientific
ISBN: 1908977183
Category : Technology & Engineering
Languages : en
Pages : 444
Book Description
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.

Three-Dimensional Velocity and Vorticity Measuring and Image Analysis Techniques
Author: Th. DracosPublisher: Springer Science & Business Media
ISBN: 9401587272
Category : Science
Languages : en
Pages : 322
Book Description
The contents of this volume reflect to a large extent the efforts made by a group of Institutes at the ETH Zürich to develop new techniques for measurements of flows in fluids in the last decade. The motivation came from the study of tr~sport and mixing processes in natural and industrial systems. One of the characteristic properties of turbulence is its high mixing efficiency. The techniques developed are therefore suitable, although not exclusively, for turbulence measurements. They can be subdivided into point-measurements and field-measurements. The aim of the point-measurements developed is to determine the three components of the velocity and all their first derivatives with good temporal resolution and accuracy in turbulent flows. The old and weIl established method of hot-wire anemometry was used for this purpose. One of the main achievements in this context is the construction of miniature multi-wire probes. This technique was introduced to the Institute of Hydromechanics and Water Resources Management of ETH Zürich by Profs. A. Tsinober and E. Kit from Tel-Aviv University. This was made possible by the generous financial support by ETH, for which I would like to express my gratitude on this occasion. In addition, Dr. F.E. Joergensen from DANTEC contributed an example of recent developments in the hardware ofConstant Temperature Anemometry (CTA), for which I am very thankful.
Imaging Measurement Methods for Flow Analysis

Category : Technology & Engineering
Languages : en
Pages : 335
Book Description
In 2003 the German Research Foundation established a new priority programme on the subject of “Imaging Measurement Methods for Flow Analysis” (SPP 1147). This research programme was based on the fact that experimental ?ow analysis, in addition to theory and numerics, has always played a predominant part both in ?ow research and in other areas of industrial practice. At the time, however, c- parisons with numerical tools (such as Computational Fluid Dynamics), which were increasingly used in research and practical applications, soon made it clear that there are relatively few experimental procedures which can keep up with state-of-the-art numerical methods in respect of their informative value, e.g. with regard to visu- spatial analysis or the dynamics of ?ow ?elds. The priority programme “Imaging Measurement Methods for Flow Analysis” was to help close this development gap. Hence the project was to focus on the investigation of ef?cient measurement me- ods to analyse complex spatial ?ow ?elds. Speci?c cooperations with computer sciences and especially measurement physics were to advance ?ow measurement techniques to a widely renowned key technology, exceeding the classical ?elds of ?uid mechanics by a long chalk.

Optical Fiber Sensor Technology

ISBN: 1461557879
Category : Technology & Engineering
Languages : en
Pages : 445
Book Description
Progress in optical fiber sensors The field of optical fiber sensor technology is one that continues to expand and develop at a rate that could barely have been predicted a few years ago. The wealth of publications appearing in the technical literature and the burgeoning number of papers presented at the now well-established series of national and international conferences, which are attended by a wide selection of technically qualified optoelectronics professionals, gives a clear indication of both the range and scale of the devices and applications now seen in the subject. Such a rapid expansion makes it very difficult for the scientist and engineer, under pressure to be both informed and effective for an employer, to attend all these meetings, selectively read the appropriate literature and be able quickly to gain the knowledge in those specific areas which will give the best advantage for the work in hand. To that end, this volume has been planned and carefully designed to provide an essential overview, and detailed specific information, on those novel and exciting aspects of optical fiber sensor technology that have recently emerged, with particular focus on the devices and the exciting applications of this part of optoelectronic technology in the vast international measurement and instrumentation area.
