Abstract
Large-eddy simulations (LES) of propane gaseous pool fires with the eddy dissipation concept (EDC) combustion model, considering finite rate chemistry effects, are presented in this study. Two global (2-step) chemical reaction mechanisms for propane are explored with different grid resolutions. The study aims to investigate the performance of the employed approach towards predicting the flow field, the flame temperature, and the concentration of minor species (carbon monoxide). The selected mechanisms are also studied in mixture fraction space using a 0D CMC code to complement the LES simulations. The results demonstrate minor differences between the two mechanisms for the predicted flame temperature and the resulting flow field. Nevertheless, the production of CO was significantly different between the two mechanisms. In addition, the numerical predictions on coarse grids were strongly grid sensitive and could not accurately resolve the flame dynamics, illustrating the increased grid requirements associated with the use of finite rate chemistry.
