AIAA (American Institute of Aeronautics & Astronautics) Optical Diagnostics for Reacting and Non-Reacting Flows: Theory and Practice (Progress in Astronautics and Aeronautics, 264)

Optical Diagnostics for Reacting and Non-Reacting Flows serves both as a launch pad for new students of optical diagnostics seeking a “go to” book, and as a resource for the experienced diagnostician seeking to explore new techniques, or new applications of familiar techniques. Measurement techniques that exploit lasers and light-matter interactions are uniquely capable of advancing our understanding of reacting and non-reacting flows. Such (largely) noninvasive measurement approaches may be used for visualizing and quantifying key chemical species concentrations, thermodynamic properties, and fluid-dynamic parameters. The information thus generated is essential for achieving detailed understanding of fundamental chemistry and physics. Furthermore, recent years have seen the increased use of these techniques in realistic configurations/conditions to help overcome real-world engineering challenges. Target configurations for optical measurements include canonical flames and flows, high-speed wind tunnels, combustor and component test rigs, gas-turbine engines, pulsed- and rotating-detonation engines, piston engines, and other advanced propulsion, power, and fuel systems. This contributed volume provides an extensive theoretical and practical guide to use of advanced optical measurement techniques in fluids and combustion. After a brief introduction to optical diagnostic basics, the spectroscopic and imaging topics covered are Rayleigh scattering, Raman scattering, laser-induced fluorescence, various four-wave mixing techniques, laser absorption spectroscopy, laser induced breakdown spectroscopy, molecular tagging, thermographic phosphors, particulate diagnostics, spray diagnostics, absorption spectroscopy, and chemiluminescence. Additional chapters discuss novel ways of collecting and interpreting data, namely fiber and endoscopic signal generation and acquisition, multi-dimensional imaging via tomographic reconstruction, uncertainty quantification, and data analysis.
