Abstract

MILD combustion is a promising concept which combines dilution and preheating, and decreases harmful emissions like NOx. It has been applied to industrial furnaces for years, but the physical phenomena occurring are yet to be revealed. In this study, 2D and 3D DNS calculations of MILD combustion in the form of auto-igniting mixing layers were performed. Effects of different parameters like heat loss and preferential diffusion were investigated. We found that the heat loss effects are crucial in predicting ignition delay and flame structure. Furthermore, we observed that the preferential diffusion effects were present even in highly turbulent environment.
