ABSTRACT

The aim of this work is to combine Large-Eddy- Simulation (LES) and the PDF-transport method for the prediction of turbulent non-premixed flames. On the one hand the motivation is based upon the property of LES to provide a better description of complex flows than RANS (Reynolds-Averaged-Navier-Stokes) methods offer. On the other hand PDF-methods allow for exact treatment of the chemical source term, which provides a possibility to describe strong turbulence-chemistry interaction considering chemical time scales with equal or greater magnitude compared to the turbulent time scales.
The intent of this work is to combine the ability of the LES to predict scalar mixing with high accuracy and the property of PDF transport methods to describe the chemical source term in a closed form.
