Opis

Thermal radiation is an important phenomenon in many combustion processes ofpractical importance. This is especially so if the physical scale is large or the pressure is high, either or both of which features often characterize industrial equipment. Yet combustion analysts and engineers are often largely unfamiliar with the physics of thermal radiation transfer. This book focuses on the integration of heattransfer and combustion. These two subjects have traditionally been considered separate disciplines. In reality, the two are closely interwoven. The central purpose of the book is to generate an effective cross-fertilization of the two at both the fundamental and applied levels. The papers collected in this volume cover the following topics: mathematical simulations of heat transfer in reacting systems, new measurements of the radiation properties of the intervening medium and measurement techniques for them, and data and theoretical analyses whichclarify the physical nature of the complex interactions between radiation/convection heat transfer processes and the combustion and turbulence of real reacting flows.
