Large Eddy simulation of a counterflow configuration

The aim of the present work is to extend the possibilities of predicting tu rbulent activity and mixing in counterflow burners. Such burners are well s uited for the calibration and validation of combustion models. Because of t heir geometry, they allow simulations to be performed in only one dimension of space. This safes much computation time, rendering for example the simu lation of detailed chemistry possible. Here, a three dimensional LES is app lied without considering chemical reactions. Sub-grid fluctuations are mode led according to Smagorinsky. The model constant is determined dynamically by the well known Germane approach.
