This book was released on 1994 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The discrete ordinates method has evolved as a powerful tool in the analysis of radiative heat transfer in multidimensional geometries containing participating media. The discrete ordinates method does not make accurate predictions in situations involving isolated boundary sources, due to a phenomenon known as 'ray-effects'. A modified discrete ordinates (MDO) method is presented. The intensity is broken into diffuse and direct components. The direct intensity component is determined analytically, and the direct inscatter term appears as a distributed source in the transport equation for the diffuse intensity. The diffuse transport equation is solved numerically by the conventional discrete ordinates procedure. The MDO method is applied to solve the radiative transfer equation in two- and three-dimensional rectangular and cylindrical enclosures containing absorbing, emitting, and isotropically scattering media. Uniform and non-uniform diffuse loadings on the top boundary are considered. Graphical and numerical results for various geometries and loading parameters are presented. The standard discrete ordinates solution exhibits anomalies in the flux leaving the bottom. Large errors are observed when the loading area is small compared to the overall enclosure dimensions. The MDO method eliminates 'ray-effects' and significantly improves the accuracy of the predictions"--Abstract, leaf iv.

This book was released on 1972 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The exact formulations for the radiative flux and the emissive power are presented for a two-dimensional, finite, planar, absorbing and emitting, gray medium in radiative equilibrium. Exact expressions are obtained for the medium subjected to the following types of boundary conditions: (1) cosine varying diffuse, (2) cosine varying collimated, (3) constant temperature strip, and (4) the strip illuminated by a uniform collimated flux. The solutions for the physically unrealistic cosine varying models are used to construct the solutions for the more practical finite strip models. The two-dimensional equations are reduced to one-dimensional equations by the method of separation of variables. This simplification is made possible by the cosine form of the boundary radiation. The corresponding equations for the semi-infinite medium are obtained from the equations for the finite optical thick medium by letting the optical thickness become infinite. The reduced one-dimensional equations are then solved exactly by techniques from one-dimensional radiative theory for the emissive power and radiative flux at the boundaries for both the finite and semi-infinite models. A wide range of exact numerical data is presented. The cosine varying collimated boundary condition generates functions which are analogous to the one-dimensional X- and Y-functions of Chandrasekhar for the finite model and the H-function of Chandrasekhar for the semi-infinite model. These generalized functions represent the dimensionless emissive power at the boundaries and appear in the radiative flux and emissive power at the boundaries for the cosine varying diffuse model as well as for both finite strip models. The generalized H-, X- and Y-functions are tabulated exactly for a wide range of numerical values. In addition to the generalized H-, X- and Y-functions, a function analogous to the exponential integral function is introduced. Generalized exponential integral functions of the first, second, and third order are defined and the recurrence formulas and series expansions are developed. The generalized exponential integral functions are tabulated for a wide range of numerical values"--Abstract, pages ii-iii.
Download or read book Radiation Transfer written by Apresyan and published by Routledge. This book was released on 2019-07-16 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors expound on non-traditional phenomena for transfer theory, which are nevertheless of considerable interest in wave measurements, and bring the advances of transfer theory as close as possible to the practical needs of those working in all areas of wave physics. The book opens with a historical overview of the topic, then moves on to examine the phenomenological theory of radiative transport, blending traditional theory with original ideas. The transport equation is derived from first principles, and the ensuing discussion of the diffraction content of the transport equation and non-classical radiometry is illustrated by practical examples from various fields of physics. Popular techniques of solving the transport equation are discussed, paying particular attention to wave physics and computing the coherence function. The book also examines various problems which are no longer covered by the traditional radiative transfer theory, such as enhanced backscattering and weak localization phenomena, nonlinear transport problems and kinetic equations for waves. This monograph bridges the gap between the simple power balance description in radiative transfer theory and modern coherence theory. It will be of interest to researchers and professionals working across a wide range of fields from optics, acoustics and radar theory to astrophysics, radioastronomy and remote sensing, as well as to students in these areas.
Download or read book Radiative Transfer written by Hélène Frisch and published by Springer Nature. This book was released on 2022-05-26 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses analytic and asymptotic methods relevant to radiative transfer in dilute media, such as stellar and planetary atmospheres. Several methods, providing exact expressions for the radiation field in a semi-infinite atmosphere, are described in detail and applied to unpolarized and polarized continuous spectra and spectral lines. Among these methods, the Wiener–Hopf method, introduced in 1931 for a stellar atmospheric problem, is used today in fields such as solid mechanics, diffraction theory, or mathematical finance. Asymptotic analyses are carried out on unpolarized and polarized radiative transfer equations and on a discrete time random walk. Applicable when photons undergo a large number of scatterings, they provide criteria to distinguish between large-scale diffusive and non-diffusive behaviors, typical scales of variation of the radiation field, such as the thermalization length, and specific descriptions for regions close and far from boundaries. Its well organized synthetic view of exact and asymptotic methods of radiative transfer makes this book a valuable resource for both graduate students and professional scientists in astrophysics and beyond.
