Summary on Grant Application Form
This project arises from the need to find replacements for halon flame inhibitors now banned under the Montreal Protocol. We aim to develop a fundamental understanding of the inhibition of premixed laminar lames through the analysis (and numerical computation) of a generic model for an exothermic branched chain reaction system inhibited by the endothermic production of an inhibitor which acts through catalysing radical termination. The results will be obtained in a form immediately applicable to published experimental data on the inhibiting effects of mists of dissolved salts in water on hydrocarbon flames, but will also be cast in more general terms. Several reductions of the governing equations have been identified, based on the typical magnitude of certain dimensionless groups, which will also be studied to provide the building blocks for the interpretation of the full model. The possibility of oscillating or cellular flame structures in this system will be investigated and heat-loss will be considered explicitly leading to the study of burner-stabilised as well as freely-propagating flames.EngProg\
