Abstract
The capability of LES sub-grid scale modelling approaches to determine near-wall CO concentration during flame-wall interaction (FWI) is investigated through the analysis of fully-resolved simulations of premixed flame head-on quenching. Pre-tabulated lookup tables for CO based on the reduced temperature and a progress variable are shown to be a promising approach for non-adiabatic CO concentration modelling. Two commonly used generalised Flame Surface Density (FSD) models are also tested in this a priori study. It is shown that both models underpredict CO concentration during quenching. A significant increase of the displacement speed as well as a large variation of this quantity across dif..
