Abstract

The specific mechanisms by which fire suppressants influence flame properties have been determined on the basis of computer simulations. Attention is focussed on the relative contributions from physical and chemical processes. Chemical effects are most strongly manifested at low concentrations of suppressants. As their concentrations are increased, the chemical effects reach a maximum value, while the physical effects continue to increase. The use of a composite inhibitor composed of a mixture of an effective chemical inhibitor with a high heat capacity diluent may be beneficial. The relative contributions towards fire suppression from physical and chemical mechanisms are estimated near the flammability limits.
