Book Description
Describes the interaction between the fluid flow and the high temperature phenomena experienced in the hypersonic regime. Presents the principles of aerothermodynamics in nonequilibrium hypersonic flow regimes, covering theory, application and surface phenomena. Chapters 1 to 5 explain how to develop computational fluid dynamics (CFD) techniques for computing nonequilibrium, chemically reacting flows in the hypersonic regime. Chapters 6 to 8 examine the important physical phenomena that occur in hypersonic flows. The final chapter is devoted to the nonequilibrium kinetics at solid surfaces, which is useful in addressing the problems of the nonequilibrium gas-surface interactions that arise in hypersonic flight.

Book Description
A modern treatment of hypersonic aerothermodynamics for students, engineers, scientists, and program managers involved in the study and application of hypersonic flight. It assumes an understanding of the basic principles of fluid mechanics, thermodynamics, compressible flow, and heat transfer. Ten chapters address: general characterization of hypersonic flows; basic equations of motion; defining the aerothermodynamic environment; experimental measurements of hypersonic flows; stagnation-region flowfield; the pressure distribution; the boundary layer and convective heat transfer; aerodynamic forces and moments; viscous interactions; and aerothermodynamics and design considerations. Includes sample exercises and homework problems. Annotation copyright by Book News, Inc., Portland, OR

Book Description
In this book selected aerothermodynamic design problems in hypersonic vehicles are treated. Where applicable, it emphasizes the fact that outer surfaces of hypersonic vehicles primarily are radiation-cooled, an interdisciplinary topic with many implications.

Book Description
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.

Book Description
NEQPAK is a set of Fortran 77 routines and databases which are useful in the development and application of nonequilibrium flow solvers. The set includes a library of subroutines for evaluating reaction rates and the thermal and transport properties of high-temperature ionized gases. Thermal nonequilibrium may be treated by applying modules which evaluate the interactions between molecular energy modes. The interactions between vibrational and chemical relaxation may be investigated by using multiple- temperature reaction models or by applying the coupling factors suggested by contemporary theories. A utility for correlating user-supplied reaction data with the material properties database is also provided. Most of the modules are optimized for use on vector-processing machines, and have been designed for the efficient use of memory. The thermal properties database covers the range from 100 to 35,000 K, and the transport properties database extends from 300 to 30, 000 K, and the transport properties database extends from 300 to 30,000 K. This report describes the thermophysical models embodied in NEQPAK and explains how the routines may be incorporated into hypersonic CFD codes.

Book Description
The last two decades have brought two important developments for aeroth- modynamics. One is that airbreathing hypersonic flight became the topic of technology programmes and extended system studies. The other is the emergence and maturing of the discrete numerical methods of aerodyn- ics/aerothermodynamics complementary to the ground-simulation facilities, with the parallel enormous growth of computer power. Airbreathing hypersonic flight vehicles are, in contrast to aeroassisted re-entry vehicles, drag sensitive. They have, further, highly integrated lift and propulsion systems. This means that viscous eflFects, like boundary-layer development, laminar-turbulent transition, to a certain degree also strong interaction phenomena, are much more important for such vehicles than for re-entry vehicles. This holds also for the thermal state of the surface and thermal surface effects, concerning viscous and thermo-chemical phenomena (more important for re-entry vehicles) at and near the wall. The discrete numerical methods of aerodynamics/aerothermodynamics permit now - what was twenty years ago not imaginable - the simulation of high speed flows past real flight vehicle configurations with thermo-chemical and viscous effects, the description of the latter being still handicapped by in sufficient flow-physics models. The benefits of numerical simulation for flight vehicle design are enormous: much improved aerodynamic shape definition and optimization, provision of accurate and reliable aerodynamic data, and highly accurate determination of thermal and mechanical loads. Truly mul- disciplinary design and optimization methods regarding the layout of thermal protection systems, all kinds of aero-servoelasticity problems of the airframe, et cetera, begin now to emerge.
