Abstract

The non-premixed reaction of fuel with air in a mixing layer is studied using DNS. The situation is a model for the mixing-controlled combustion in a Diesel engine. We show that the combustion region can be comparably passive with respect to relatively large scale aerodynamic instabilities. However the reaction decreases the small scale turbulent energy. A flamelet analysis shows differences between two and three dimensional situations. In a first analysis, performed for the two dimensional case, no correlation of the flame-normal compressive strain rate with a flamelet-like behavior is observed.
