要約

The aim of this study is to compare three different state-of-the-art Large Eddy simulation (LES) combustion models for a reactive turbulent mixing layer. The models selected are the Flame-Wrinkling (FW) model, a Monotone Integrated LES (MILES) model in conjunction with global chemistry, and the Linear Eddy Model (LEM). The models are briefly described before results obtained from a computational investigation of a reactive turbulent mixing layer are presented and compared with experimental data. Finally, a discussion is provided concerning the intrinsic natures and capabilities of these models.
