This volume collects the results of a workshop held at Aachen, West-Germany, Oct. 12 - Oct. 14, 1981. The purpose in bringing together scientists actively working in the field of numerical methods in flame propagation was two-fold: 1. To confront them with recent results obtained by large ac tivation-energy asymptotics and to check these numerically. 2. To compare different numerical codes and different trans port models for flat flame calculations with complex che mistry. Two test problems were formulated by the editors to meet these objectives. Test problem A was an unsteady propagating...

The combustion of fossil fuels remains a key technology for the foreseeable future. It is therefore important to understand combustion mechanisms, in particular, the role of turbulence within this process. This monograph presents a thorough introduction to the field of turbulent combustion. After an overview of modeling approaches, Peters considers the three distinct cases of premixed, nonpremixed, and partially premixed combustion, respectively. By demonstrating the current theories of turbulent combustion within a cohesive presentation, this book makes a unified contribution to engineering...

In general, combustion is a spatially three-dimensional, highly complex physi co-chemical process oftransient nature. Models are therefore needed that sim to such a degree that it becomes amenable plify a given combustion problem to theoretical or numerical analysis but that are not so restrictive as to distort the underlying physics or chemistry. In particular, in view of worldwide efforts to conserve energy and to control pollutant formation, models of combustion chemistry are needed that are sufficiently accurate to allow confident predic tions of flame structures. Reduced kinetic...
