Reacting Flows — Introductory Remarks

Conference paper

Abstract

Our understanding of non-reacting turbulent flows is rudimentary enough. One might question whether research into reacting turbulent flows can make much progress when such a basic understanding of turbulence is lacking. The non-linearity inherent in all but the simplest chemical reactions compounds an already highly non-linear problem as do the often associated phenomena of heat release, strong density gradient, radiant heat transfer and two-phase transport. Such difficulties are in themselves a challenge. There are, however, strong practical incentives for endeavours in this field. Unlike non-reacting flows, scale modeling of combustion systems is highly unsatisfactory and measurements in the hostile combustion environment pose very great problems of access, probe integrity and interference with the flow. Development of combustion chambers such as for diesel engines and glass melting furnaces has progressed by trial and error in the absence of even rudimentary knowledge of the flow patterns so essential to mixing, combustion and heat transport. The advent of three-dimensional computer models of such furnaces and combustion chambers, albeit rather crude for their details at this stage, is proving to be of immense benefit in the insight that they are able to give designers and developers who have for so long been blind-folded.
