This book was released on 2018-07-02 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-intrusive techniques for the dynamic measurement of gas flow properties such as density, temperature and velocity, are needed in the research leading to the development of new generation high-speed aircraft. Accurate velocity, temperature and density data obtained in ground testing and in-flight measurements can help understand the flow physics leading to transition and turbulence in supersonic, high-altitude flight. Such non-intrusive measurement techniques can also be used to study combustion processes of hydrocarbon fuels in aircraft engines. Reliable, time and space resolved temperature measurements in various combustor configurations can lead to a better understanding of high temperature chemical reaction dynamics thus leading to improved modeling and better prediction of such flows. In view of this, a research program was initiated at Polytechnic University's Aerodynamics Laboratory with support from NASA Lewis Research Center through grants NAG3-1301 and NAG3-1690. The overall objective of this program has been to develop laser-based, non-contact, space- and time-resolved temperature and velocity measurement techniques. In the initial phase of the program a ND: YAG laser-based dual-line Rayleigh scattering technique was developed and tested for the accurate measurement of gas temperature in the presence of background laser glare. Effort was next directed towards the development of a filtered, spectrally-resolved Rayleigh/Mie scattering technique with the objective of developing an interferometric method for time-frozen velocity measurements in high-speed flows utilizing the uv line of an ND: YAG laser and an appropriate molecular absorption filter. This effort included both a search for an appropriate filter material for the 266 nm laser line and the development and testing of several image processing techniques for the fast processing of Fabry-Perot images for velocity and temperature information. Finally, work was also carried out for the development of a.

Download or read book Molecular Scattering of Light written by I. L. Fabelinskii and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of the laser and the subsequent expansion of research in the field of molecular scattering of light tend to ob scure the vast literature that accumulated on this subject during th'e last fifty years. The appearance of the Russian edition of Dr. Fabelinskii's book, just as this laser-induced explosion in light-scattering research took place, served to put the earlier work in its proper perspective. However, the book lacked any appreci able coverage of the laser work. Fortunately, Dr. Fabelinskii has taken advantage of the time between the appearance of the Russian text and its translation into English to expand greatly the sections devoted to areas in which laser research has made such interesting and vital additions, At the same time, revisions and insertions have been made throughout the text, so that the English translation is virtually a second edition of this useful work. The translator wishes to express his thanks here to Dr. Fa belinskii for making the revisions, corrections, and additions availahle for the English language work. He is also grateful to his graduate student, Mark B. Moffett, who prepared the index and who, during the course of its preparation, made a large number of crit ical comments and corrections that have enhanced the quality of the final product.

Download or read book Atmospheric Transmission Emission and Scattering written by Thomas G. Kyle and published by Elsevier. This book was released on 2013-10-24 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduces the physical processes and meteorology required to understand the behaviour of light and radiation in the atmosphere. Integrating the treatment of atmospheric optics from the ultraviolet to the microwave, the book presents a detailed overview, together with discussions, on the associated meteorology and atmospheric composition, which gives the meteorological background necessary to deal with the varying conditions found in the real atmosphere. Mathematical details provide a concise description of results thus allowing readers with a knowledge of meteorology or a single wavelength region to comprehend the transmission, emission and scattering in all wavelength regions. Rayleigh and Mie scattering are covered as well as the aerosol and raindrop distributions found in the atmosphere. Detailed models of the atmosphere and the distribution of trace gases are supplied, and finally a chapter is devoted to standardised software and available data bases.
Download or read book Statistical Mechanics Kinetic theory and Stochastic Processes written by C.V. Heer and published by Elsevier. This book was released on 2012-12-02 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical Mechanics, Kinetic Theory, and Stochastic Processes presents the statistical aspects of physics as a "living and dynamic" subject. In order to provide an elementary introduction to kinetic theory, physical systems in which particle-particle interaction can be neglected are considered. Transport phenomena in the free-molecular flow region for gases and the transport of thermal radiation are discussed. Discrete random processes such as random walk, binomial and Poisson distributions, and throwing of dice are studied by means of the characteristic function. Comprised of 11 chapters, this book begins with an introduction to the mass point gas as well as some elementary properties of space and velocity distributions. The discussion then turns to radiation and its interaction with an atom; probability, statistics, and conditional probability; intermolecular interactions; transport phenomena; and statistical thermodynamics. Molecular systems at low densities are also considered, together with non-ideal and real gases; liquids and solids; and stochastic processes, noise, and fluctuations. In particular, the response of atoms and molecules to perturbations and scattering by crystals, liquids, and high-pressure gases are examined. This monograph will be useful for undergraduate students, practitioners, and researchers in physics.
