Efficient suppression of flames by condensed-phase
agents (e.g., dry powder, water, etc.) requires a basic
understanding of the rate-controlling physical, thermal
and chemical processes. A steady, laminar, non-premixed
flame, established within the mixing layer of a
counterflow of methane and air, is used here to
numerically determine the rate controlling processes
associated with flame extinction by fine water droplets.
Although experiments are planned to validate the model,
only the numerical results with water droplets
introduced with the air stream are reported here.
