Heat Transfer In Radiating And Combusting Systems: Proceedings Of Eurotherm Seminar No. 17, 8–10 October 1990, Cascais, Portugal (eurotherm Seminars)

This volume contains the selected papers presented at the EUROTHERM SEMINAR No. 17 - Heat Transfer in Radiating and Combusting Systems held at Cascais from October 8th- 10th, 1990. The EUROTHERM COMMITTEE was created by representatives of the member countries of the European Communities for the organization and coordination of European Scientific events in the field of thermal sciences and their applications. The book is focused on the integration of the heat transfer 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 fertilisation of the two at both the fundamental and applied levels. The book reports on: mathematical simulations of heat transfer in reacting systems, new measurements of and measurement techniques for the radiation properties of the intervening medium, and data and theoretical analyses which clarify the physical nature of the complex interactions between the radiation/convection heat transfer processes and the combustion and turbulence of real reacting flows.

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.
