SINOPSIS

In addition to the complexities arising in non-reacting turbulent shear flows, the presence of highly exothermic chemical reactions introduces new difficulties. This central problem in combustion raises many fundamental issues with important practical applications. Progress in this field has been quite substantial. Advances on the theoretical level have been accompanied by significant developments in experimentation with laser diagnostics, high speed imaging and numerical data processing. Advances in computational combustion and more specifically in large eddy simulations have had a profound effect on scientific research in this field and on engineering applications. Starting with a brief tour of major issues in combustion, this article focuses on modeling strategies. The emphasis will be placed on modern approaches based on large eddy simulation. Issues related to a suitable description of chemistry and the possible use of tabulation methods will be specifically discussed and illustrated by examining selected topics of fundamental interest.
