Modelling turbulent reacting jets under MILD combustion conditions

A turbulent non-premixed Methane/Hydrogen (1/1 by volume) flames issuing from a jet in hot, low oxygen content coflow, was modelled using transport PDF (TPDF) approach. A comparison between the TPDF results and detailed experimental data of temperature, OH and CO is presented for flames with different oxygen level in the hot coflow (oxygen mass-fraction of 9%, 6%, and 3%). Different kinetics mechanisms were also used. Results from a previous study using the eddy-dissipation concept (EDC) model are also presented. A comparison in performance between the TPDF and EDC models is presented.
