The problem of heat transfer from media that absorb and scatter thermal radiation was studied analytically, and the theory of thermal radiation is presented in a form useful for application to the radiant heat transfer problems. The basic equation of radiant heat transfer which governs the radiation field in a media that absorbs, emits, and scatters thermal radiation was derived. The mathematical analogy between thermal radiation and neutron transport is pointed out, and a few illustrations of the applicability of the solutions obtained for neutron transport problems to the radiative transfer problems are given.

The problem of heat transfer from media that absorb and scatter thermal radiation was studied analytically, and the theory of thermal radiation is presented in a form useful for application to the radiant heat transfer problems. The basic equation of radiant heat transfer which governs the radiation field in a media that absorbs, emits, and scatters thermal radiation was derived. The mathematical analogy between thermal radiation and neutron transport is pointed out, and a few illustrations of the applicability of the solutions obtained for neutron transport problems to the radiative transfer problems are given. The derivation of the integral equations for radiant heat exchange in a geneal enclosure composed of a system of surfaces separated by an absorbing and scattering media are presented. The enclosure walls under consideration can reflect specularly and the scattering from the medium is not considered to be isotropic. The equation for the conservation of energy, including contributions due to thermal radiation, was derived by evaluating the energy transported into an imaginary closed surface fixed in space and then by applying Gauss's divergence theorem. The formulations developed are then used to gain insight into the problem by considering a few simple physical situations and obtaining numerical results for the grey case only. The Rosseland approximation for the radiant flux vector is employed in the study of Couette flow, and it is found that for large optical thicknesses the calculated temperature distributions agree well with those predicted by the exact formulation. Numerical solutions of the boundary layer equations for the flow of a radiating media along a wedge were obtained. The effect of radiation is to decrease the temperature gradient for both the hot and the cool walls; however, the heat transfer is affected only little. The validity of the diffusion approximation for radiation in boundary layer problems is limited, and should be used with caution only in situations where the mean free path of radiation is much smaller than the thermal bouadary layer thickness. The transport of radiant energy between two parallel plates separated by an absorbing and scattering media is studied. The temperature distributions were obtained by solving the nonhomogeneous Milne integral equation of the first kind. It was found that the polynomial approximation for the black body emissive power is satisfactory for all values of the optical thickness. The transport of energy by simultaneous conduction and radiation in a one-dimensional system was considered. A nonlinear integral equation governing the temperature distribution in an absorbing media was solved, and it is shown that the temperature distribution is strongly dependent on the optical thickness of the slab and on the dimensionless parameter, N, which determines the relative role of energy transfer by conduction to that by radiation. The presence of radintion generally increases the heat transfer by conduction. (auth).

Providing a comprehensive overview of the radiative behavior and properties of materials, the fifth edition of this classic textbook describes the physics of radiative heat transfer, development of relevant analysis methods, and associated mathematical and numerical techniques. Retaining the salient features and fundamental coverage that have made it popular, Thermal Radiation Heat Transfer, Fifth Edition has been carefully streamlined to omit superfluous material, yet enhanced to update information with extensive references. Includes four new chapters on Inverse Methods, Electromagnetic Theory, Scattering and Absorption by Particles, and Near-Field Radiative Transfer Keeping pace with significant developments, this book begins by addressing the radiative properties of blackbody and opaque materials, and how they are predicted using electromagnetic theory and obtained through measurements. It discusses radiative exchange in enclosures without any radiating medium between the surfaces—and where heat conduction is included within the boundaries. The book also covers the radiative properties of gases and addresses energy exchange when gases and other materials interact with radiative energy, as occurs in furnaces. To make this challenging subject matter easily understandable for students, the authors have revised and reorganized this textbook to produce a streamlined, practical learning tool that: Applies the common nomenclature adopted by the major heat transfer journals Consolidates past material, reincorporating much of the previous text into appendices Provides an updated, expanded, and alphabetized collection of references, assembling them in one appendix Offers a helpful list of symbols With worked-out examples, chapter-end homework problems, and other useful learning features, such as concluding remarks and historical notes, this new edition continues its tradition of serving both as a comprehensive textbook for those studying and applying radiative transfer, and as a repository of vital literary references for the serious researcher.

Radiative Heat Transfer in Two-Phase Media is devoted to discussing and further developing the radiative heat transfer theory. It provides thorough coverage of studies of physical processes in emitting two-phase media as applied to combustion chambers of heat power plants. Numerical methods are developed, and a number of reliable approximate solutions to radiative heat transfer problems are proposed. Widely accepted thermophysical concepts, such as effective temperature, effective emissivity of heat carriers, and thermal efficiency of screens, are covered in detail. The book also provides programs for computing spectroscopic characteristics of emitting two-phase media, which are useful for solving complex radiative heat transfer problems. Radiative Heat Transfer in Two-Phase Media is an important book for the library of any heat transfer specialist.
