This book presents a comprehensive guide to the modeling of thermal radiation, covering the current advanced methods in this field involved in both engineering applications and physical sciences. It guides the reader through the interaction of electromagnetic radiation, on the one hand with gases, plasmas, liquids, or solids at all spatial scales, from those of atoms, molecules, or electrons to that of a continuous medium, and, on the other hand, with divided media, statistically upscaled to the scale of spatially superimposed continuous media, characterized by spatial presence probabilities.

The book is divided into four parts, the first of which deals with radiation-matter interactions at an elementary scale (photon, molecule, particle or wave), followed by the radiative intensity evolution along trajectories through a semi-transparent continuous Beerian medium. Part 2 develops the radiative properties of an opaque body, and of a transparent and a semi-transparent medium and introduces simple analytical models of radiative transfer. Part 3 characterizes the radiative properties of all the media encountered in applications: one phase media (gases, plasmas, and dense media including sets of particles) and two phase media (macro-porous media, often non-Beerian). Part 4 focuses on the couplings of radiation with the other heat transfer modes within one phase media, in particular in the case of forced and free turbulent flows. Special attention is also paid to radiative transfer within statistically modeled macro-porous media and the associated numerical treatments. Advanced ray-tracing and Monte-Carlo numerical methods are presented in detail.

Jean Taine is a former student of École Normale Supérieure of University Paris-Saclay. He obtained his master's degree in Atomic and Statistical Physics at École Normale Supérieure and became Docteur ès Sciences in Chemical Physics at University Paris-Saclay under the supervision of Magdeleine Huetz-Aubert. He served as professor of Physics at CentraleSupélec (CS), teaching mainly statistical physics and heat transfer. He has published a textbook on general heat transfer (Transferts Thermiques, 6 editions), and a short version “A first course in heat transfer”. Since 1990, he founded and animated, within the Molecular and Macroscopic Energetics, Combustion laboratory (EM2C) of CS, a research group focused on the physics of energy transfer. His research topics have been, at different times, spectroscopy at high temperature, radiative transfer in one-phase media and couplings with turbulent flows and combustion, statistical characterizations of macro-porous media and radiative transfer in these media. Jean Taine also served as editor for different journals, in particular in the International Journal of Heat and Mass Transfer, and was in charge of all the fields of engineering at the research department of the French Ministry of Research. 

Jean-Michel Hartmann is a former student of CentraleSupélec where, during his last year in this school, he specialized in Heat Transfer. He then benefited from lectures given by Jean Taine, under the supervision of whom he then decided to prepare a PhD in the field of high temperature molecular spectroscopy, after which he was hired by the Centre National de la Recherche Scientifique. After about 8 years in the Molecular and Macroscopic Energetics, Combustion laboratory, he moved several times to other research groups, roughly every 10 years, and is currently at the Laboratoire de Météorologie Dynamique at École Polytechnique. During all these years, his main interest has remained in gas spectroscopy, focussing on the effects of pressure on the shape of molecular absorption spectra. However, influenced by topics dealt with in the various laboratories that hosted him, he also developed theoretical research and skills in atmospheric radiative transfer and remote sensing, the modeling of spectra of molecules confined in sub-micron porous media, and the manipulation of molecules with intense laser fields. Jean-Michel Hartmann participated in about 250 articles in peer reviewed international journals and is co-author of the two editions of the book “Collisional Effects On Molecular Spectra: Experiments and models, consequences for applications”.
