Radiation Gas Dynamics


Book Description

When the temperature of a gas is not too high and the density of a gas is not too low, the transfer of heat by radiation is usually negligibly small in comparison with that by conduction and convection. However, in the hypersonic flow of space flight, particularly in the re-entry of a space vehicle, and in the flow problem involving nuclear reaction such as in the blast wave of nuclear bomb or in the peaceful use of the controlled fusion reaction, the temperature of the gas may be very high and the density of the gas may be very low. As a result, thermal radiation becomes a very important mode of heat transfer. A complete analysis of such high temperature flow fields should be based upon a study of the gasdynamic field and the radiation field simultaneously. Hence during the last few years, considerable efforts have been made to study such interaction problems between gasdynamic field and radiation field and a new title, Radiation Gasdynamics, has been suggested for this subject. Even though radiative transfer has been studied for a long time by astro physicists, the interaction between the radiation field and the gadsynamic field has been only extensively studied recently.







Modern Developments in Gas Dynamics


Book Description

During the last decade, the rapid growth of knowledge in the field of fluid mechanics and heat transfer has resulted in many significant ad vances of interest to students, engineers, and scientists. Accordingly, a course entitled "Modern Developments in Fluid Mechanics and Heat Transfer" was given at the University of California to present significant recent theoretical and experimental work. The course consisted of seven parts: I-Introduction; II-Hydraulic Analogy for Gas Dynamics; 111- Turbulence and Unsteady Gas Dynamics; IV-Rarefied and Radiation Gas Dynamics; V-Biological Fluid Mechanics; VI-Hypersonic and Plasma Gas Dynamics; and VII-Heat Transfer in Hypersonic Flows. The material, presented by the undersigned as course instructor and by various guest lecturers, could easily be adapted by other universities for use as a text for a one-semester senior or graduate course on the subject. Due to the extensive notes developed during the University of California course, it was decided to publish the material in three volumes, of which the present is the first. The succeeding volumes will be entitled "Selected Topics in Fluid and Bio-Fluid Mechanics" and "Introduction to Steady and Unsteady Gas Dynamics." Finally, I must express a word of appreciation to my wife Irene and to my children, Wellington Jr. and Victoria, who made it possible for me to write and edit this book in the very quiet atmosphere of our home.

An Introduction to High Temperature Radiation Gas Dynamics


Book Description

This document is intended as an introduction to the study of radiative transfer and hydrodynamics in the high temperature (>10,000K) regime. Most of the basic references on radiative transfer are oriented to astrophysics. It is always difficult for workers in other areas of research to cull from this literature those aspects of the subject relevant to their own interests. The purpose of this document is to present the basic principles of radiation gas dynamics from the point of view of weapons physics. The first chapter is concerned with the radiation field alone. The transfer equation is derived in its various forms, and the general formulation of radiant energy transfer in materials is discussed. The second chapter describes the various mechanisms by which the radiation field interacts with a material medium. This section, therefore, provides an introduction to the general problem of opacities. The third chapter presents the basic theory of hydrodynamics and the influence of radiation fields on fluid motion. These chapters cover the three fundamental aspects of the subject: the state of the radiation field, the radiation-material interaction, and the motion of the material. (Author).




Handbook of Generalized Gas Dynamics


Book Description

THE FACT that most books on gas dynamics include separate tables for each simplified flow process casts a shadow of inadequacy over the conventional approach. Why is each process treated as though it were entirely unrelated to the others? Why isn't there, we asked, a generalized approach based on fundamental equations which act as progenitors for the specific equations of all the simplified flow processes, and which provide insight to more general flow processes? As our solution to the above dilemma, we present a complete treatment of one-dimensional gas dynamics, stressing a fundamental approach. A unified description of this subject is accomplished by means of a single numerical table applicable to the particular gas under study. Separate treatments for the various flow processes are thus combined into one all-encompassing analysis. These tables are intended for the large group of practicing engineers, of which we are members, who daily must solve routine problems in gas dynamics. Aero dynamic, chemical, and mechanical engineers, as well as students of thermo dynamics and gas dynamics, should find these tables useful. The book is divided into five parts. In Chapter 1, we present a generalized compressible flow function r, which is shown to have direct application in the treatment of many simplified one-dimensional flow processes.




Gas Dynamics


Book Description

This book lays the foundations of gas- and fluid dynamics.The basic equations are developed from first principles, building on the (assumed) knowledge of Classical Mechanics. This leads to the discussion of the mathematical properties of flows, conservation laws, perturbation analysis, waves and shocks. Most of the discussion centers on ideal (frictionless) fluids and gases. Viscous flows are discussed when considering flows around obstacles and shocks. Many of the examples used to illustrate various processes come from astrophysics and geophysical phenomena.

Radiation and Reentry


Book Description

Radiation and Reentry is an integrated review of a series of publications dealing with radiative transfer theory, applied spectroscopy, radiation gas dynamics, and ablation phenomena. This book contains seven chapters and begins with a presentation of opacity calculations under conditions for which detailed considerations of spectral line structures and widths are not required. The discussion then shifts to the basic methods involved in the formulation of radiative transfer problems; origin and definition of the Planck and Rosseland mean free paths; the conservation equations for reacting, multicomponent gas mixtures with proper allowance for radiative energy flux; and similarity parameters in radiation gas dynamics. These topics are followed by a summary of data relevant to the optically thick, optically thin, and isothermal cases for air in local thermodynamic equilibrium. A chapter describes the radiative properties of spherical particles and their particle size distributions. Another chapter considers the estimation of radiant-energy transmission through atmosphere. The concluding chapters explore the radiation transfer effects on the flow about a re-entry body and the specific problems of the effect of radiant-energy transfer on acoustic waves, shock wave structure, and shock and boundary layers. These chapters also examine the theoretical and experimental studies on the ablation of re-entry vehicles. This book is of great value to educated nonspecialists who are interested in the application of radiation field to high-speed atmospheric entry.




Fundamentals of Thermodynamics, Thermochemistry, and Gas Dynamics


Book Description

The book discusses processes common in the three major fields of thermal science - Thermodynamics, Thermochemistry, and Gas Dynamics. Chapter topics include heat, work and entropy transfers in equilibrium, non-equilibrium, and local-equilibrium systems; calculus of multi-variable functions; equations of state of ideal and real gases; heat capacities of ideal and real gases and their mixtures; the Gibbs Equations; phase-equilibrium and multi-phase transitions; thermodynamic cycles and their efficiencies; fluxes and flow rates, subsonic and supersonic flows, and gas-dynamic shock waves; chemical equilibrium and rates of chemical reactions; the dissipation of energy in real systems, their exergies, and the available work. Part of the book discusses important systems of units used in science and engineering. Scattered through the text are numerous illustrative problems with solutions intended to help readers increase their understanding of the studied concepts and methods. Since thermal processes are important in many areas of science and technology, the book will be useful to students and professionals working in the areas, including the rapidly increasing number of those who work on multi-disciplinary projects but have no extended training in thermal sciences.
