Available in PDF, EPUB and Kindle. Book excerpt: Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.

Download or read book Laser Induced Fluorescence Measurements and Modeling of Nitric Oxide in High Pressure Premixed Flames written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-25 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser-induced fluorescence (LIF) has been applied to the quantitative measurement of nitric oxide (NO) in premixed, laminar, high-pressure flames. Their chemistry was also studied using three current kinetics schemes to determine the predictive capabilities of each mechanism with respect to NO concentrations. The flames studied were low-temperature (1600 less than T less than 1850K) C2H6/O2/N2 and C2H6/O2/N2 flames, and high temperature (2100 less than T less than 2300K) C2H6/O2/N2 flames. Laser-saturated fluorescence (LSF) was initially used to measure the NO concentrations. However, while the excitation transition was well saturated at atmospheric pressure, the fluorescence behavior was basically linear with respect to laser power at pressures above 6 atm. Measurements and calculations demonstrated that the fluorescence quenching rate variation is negligible for LIF measurements of NO at a given pressure. Therefore, linear LIF was used to perform quantitative measurements of NO concentration in these high-pressure flames. The transportability of a calibration factor from one set of flame conditions to another also was investigated by considering changes in the absorption and quenching environment for different flame conditions. The feasibility of performing LIF measurements of (NO) in turbulent flames was studied; the single-shot detection limit was determined to be 2 ppm. Reisel, John R. and Laurendeau, Normand M.

Download or read book Aerosol Sampling written by James H. Vincent and published by John Wiley & Sons. This book was released on 2007-04-16 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive account of the important field of aerosol sampling as it is applied to the measurement of aerosols that are ubiquitous in occupational and living environments, both indoor and outdoor. It is written in four parts: Part A (8 chapters) describes the current knowledge of the physical science that underpins the process of aerosol sampling. Part B (4 chapters) presents the basis of standards for aerosols, including in particular the link with human exposure by inhalation. Part C (8 chapters) covers the development of practical aerosol sampling instrumentation, and how technical designs and methods have evolved over the years in order that aerosol sampling may be carried out in a manner matching the health-related and other criteria that have been proposed as parts of standards. Finally Part D (3 chapters) describes how a wide range of aerosol sampling instruments have performed when they have been applied in the field in both occupational and ambient atmospheric environments, including how different instruments, nominally intended to measure the same aerosol fraction, compare when used side-by-side in the real world. The book is intended to draw together all that is known about aerosol sampling – about the science and across a very wide range of applications – for the benefit of researchers and practitioners in occupational and environmental health and hygiene, aerosol scientists and engineers, as well as graduate-level students in these fields. In addition, the text will be of interest to environmental and occupational epidemiologists, atmospheric scientists, and occupational and environmental health policy specialists, including all those around the world engaged in the processes of setting standards for airborne particulate contaminants.

Download or read book Unusual Laser Excitations 5 890 6 520 A of the B2 Sigma Electronic State of CN in an Atmospheric Pressure Flame written by J. A. Guthrie and published by . This book was released on 1997-06-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CN radical plays an important role in the chemistry of nitramine propellant flames. Diagnostic methods for detection of this radical are therefore important for studies of its role in propellant combustion experiments. In this work, CN laser induced fluorescence (LIF) in an atmospheric pressure flame was studied. The first such flame study involving observation of LIF in the strong CN B-X violet system, near 3880 A, but with excitation using strong, fundamental dye laser outputs, near 6000 A, is reported. Excitation at significantly longer wavelengths (smaller photon energy) than LIF observation wavelengths is unusual. Because the high intensity fundamental outputs of dye lasers may be used, these excitations could ultimately prove to be very effective diagnostic methods for this species. Subsequent investigation of the spectra has revealed that at least four distinct excitation processes, some of which involve molecular collisions, are responsible for the observed LIF as the laser is scanned in this region. The observed spectra reveal some of the unexpected effects of collisions and laser intensity on absorption and fluorescence in this molecule.
