Large Eddy Simulation of a Counterflow Configuration

The aim of the present work is to extend the possibilities of predicting turbulent activity and mixing in counterflow burners. Such burners are well suited for the calibration and validation of combustion models. Because of their geometry, they allow simulations to be performed in only one dimension of space. This safes much computation time, rendering for example the simulation of detailed chemistry possible. Here, a three dimensional LES is applied without considering chemical reactions. Sub‐grid fluctuations are modeled according to Smagorinsky. The model constant is determined dynamically by the well known Germano approach.
