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
Supersonic/hypersonic Aerodynamics and Heat Transfer for Projectile Design Using Viscous-inviscid Interaction
An aerodynamic design code for axisymmetric projectiles has been developed using a viscous-inviscid interaction scheme. Separate solution procedures for inviscid (Euler) and viscous (boundary layer) flowfields are coupled by an iterative solution procedure. This code yields body surface flow profiles in less than one minute of run time on minicomputers. These surface profiles represent converged solutions to both the inviscid and viscous equations. the capability of computing local reverse flow regions is included. The procedure is formulated for supersonic and hypersonic Mach numbers including both laminar and turbulent flow. In addition, aerodynamic heating equations are used to compute heat transfer coefficient and local Stanton number from flow profiles. Computed surface pressure profiles for Mach numbers 2 thru 6 are compared to wind tunnel measurements on cone-cylinder-flare projectiles. Computed surface heat transfer coefficients are compared to results obtained from wind tunnel measurements on cone-cylinder-flare, flat plate, and blunt-cone models at Mach numbers 5 and 10. Keywords: Hypersonic flow; Computational aerodynamics; Boundary layers; Heat transfer; Projectile design.
Hypersonic and High Temperature Gas Dynamics
This book is a self-contained text for those students and readers interested in learning hypersonic flow and high-temperature gas dynamics. It assumes no prior familiarity with either subject on the part of the reader. If you have never studied hypersonic and/or high-temperature gas dynamics before, and if you have never worked extensively in the area, then this book is for you. On the other hand, if you have worked and/or are working in these areas, and you want a cohesive presentation of the fundamentals, a development of important theory and techniques, a discussion of the salient results with emphasis on the physical aspects, and a presentation of modern thinking in these areas, then this book is also for you. In other words, this book is designed for two roles: 1) as an effective classroom text that can be used with ease by the instructor, and understood with ease by the student; and 2) as a viable, professional working tool for engineers, scientists, and managers who have any contact in their jobs with hypersonic and/or high-temperature flow.
