The capability for localized flow control in high speed flows using laser energy deposition has been investigated in a collaborative computational and experimental program. Three proposed applications have been comprehensively studied. First, two models of laser energy deposition in air have been developed and validated by comparison with experiment. The first model is an engineering approach wherein the laser energy deposition is treated as an energy release in a perfect gas. The second model is a detailed physical approach which incorporates real gas chemistry with an eleven species model of air. Comparison with experimental measurements of static temperature, density and velocity (one-component) show good agreement with both models outside the plasma region. Second, a detailed 3-D simulation of laser energy deposition upstream of intersecting shocks at Mach 3.45 demonstrated the capability to force transition from Mach Reflection (MR) to Regular Reflection (RR) in the Dual Solution Domain. This result is particularly important for control of MR to RR transition in high speed inlets for scramjet-powered air vehicles. A companion experimental study showed a momentary reduction in the Mach stem height by 70%, but a Mach Reflection was recovered apparently due to freestream turbulence. Third, detailed 3-D simulations of laser energy deposition upstream of an isolated sphere and an Edney IV interaction at Mach 3.45 were performed. Results show the fundamental features observed in the accompanying experiments.

Aerodynamic Heating in Supersonic and Hypersonic Flows: Advanced Techniques for Drag and Aero-heating Reduction explores the pros and cons of different heat reduction techniques on other characteristics of hypersonic vehicles. The book begins with an introduction of flow feature around the forebody of space vehicles and explains the main parameters on drag force and heat production in this region. The text then discusses the impact of severe heat production on the nose of hypervelocity vehicles, different reduction techniques for aerodynamic heating, and current practical applications for forebody shock control devices. Delivers valuable insight for aerospace engineers, postgraduate students, and researchers. - Presents computational results of different cooling systems for drag and heat reduction around nose cones - Explains mechanisms of drag reduction via mechanical, fluidic, and thermal systems - Provides comprehensive details about the aerodynamics of space vehicles and the different shock features in the forebody of super/hypersonic vehicles - Describes how numerical simulations are used for the development of the current design of forebody of super/hypersonic vehicles

In its first centennial, aerospace has matured from a pioneering activity to an indispensable enabler of our daily life activities. In the next twenty to thirty years, aerospace will face a tremendous challenge - the development of flying objects that do not depend on fossil fuels. The twenty-three chapters in this book capture some of the new technologies and methods that are currently being developed to enable sustainable air transport and space flight. It clearly illustrates the multi-disciplinary character of aerospace engineering, and the fact that the challenges of air transportation and space missions continue to call for the most innovative solutions and daring concepts.

Compressibility, Turbulence and High Speed Flow introduces the reader to the field of compressible turbulence and compressible turbulent flows across a broad speed range, through a unique complimentary treatment of both the theoretical foundations and the measurement and analysis tools currently used. The book provides the reader with the necessary background and current trends in the theoretical and experimental aspects of compressible turbulent flows and compressible turbulence. Detailed derivations of the pertinent equations describing the motion of such turbulent flows is provided and an extensive discussion of the various approaches used in predicting both free shear and wall bounded flows is presented. Experimental measurement techniques common to the compressible flow regime are introduced with particular emphasis on the unique challenges presented by high speed flows. Both experimental and numerical simulation work is supplied throughout to provide the reader with an overall perspective of current trends. - An introduction to current techniques in compressible turbulent flow analysis - An approach that enables engineers to identify and solve complex compressible flow challenges - Prediction methodologies, including the Reynolds-averaged Navier Stokes (RANS) method, scale filtered methods and direct numerical simulation (DNS) - Current strategies focusing on compressible flow control

This book highlights the latest progress in pulsed discharge plasmas presented by front-line researchers worldwide. The science and technology surrounding pulsed discharge plasmas is advanced through a wide scope of interdisciplinary studies into pulsed power and plasma physics. Pulsed discharge plasmas with high-power density, high E/N and high-energy electrons can effectively generate highly reactive plasma. Related applications have gathered strong interests in various fields. With contributions from global scientists, the book elaborates on the theories, numerical simulations, diagnostic methods, discharge characteristics and application technologies of pulsed discharge plasmas. The book is divided into three parts with a total of 35 chapters, including 11 chapters on pulsed discharge generation and mechanism, 12 chapters on pulsed discharge characterization and 12 chapters on pulsed discharge applications (wastewater treatments, biomedicine, surface modification, and energy conversion, etc). The book is a must-have reference for researchers and engineers in related fields and graduate students interested in the subject.
