PDF Modelling of Turbulent Combustion

Abstract

Significant progress was made in the application of PDF-based turbulent combustion models to the Sandia pilot-jet nonpremixed flames. These PDF calculations were described in two recent papers (Xu & Pope 2000 and Tang, Xu & Pope 2000) and they are summarized in this report. The first of these works showed that the PDF method is capable of describing, quantitatively, the phenomena of local extinction and reignition (as functions of jet velocity and axial distance) that are observed in these flames. The second paper extended the methodology to include radiative heat loss, and the calculation of NO_x.
