DOWNLOAD EBOOKAerodynamic 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

DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKCompressibility, 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

DOWNLOAD EBOOKThe study examines the capability for reduction of the resonant pressure fluctuations in supersonic flow over an open rectangular cavity using repetitively pulsed energy deposition, computationally. The simulations are performed for the cases both with and without energy deposition for the unsteady flow over a three-dimensional cavity at a free stream Mach number of 1.5. The Reynolds-averaged compressible time dependent Navier Stokes equations in three dimensions are solved using the flow solver GASPex. The k-to turbulence model is used. A Gaussian temperature profile is utilized to model the energy pulse assuming the density within the spot is initially uniform. The results indicate that energy deposition reduces the pressure fluctuations changing the flow structure within the cavity.
