Abstract:

A steady, laminar, nonpremixed flame, established within the mixing layer of a counterflow of methane and air, is used here to quantify the rate-controlling physical, thermal and chemical contributions of sodium bicarbonate particles on flame extinction. The basic understanding obtained from this effort is expected to benefit development of enhanced condensed-phase fire suppressants. A brief description of the present experimental and theoretical/computational efforts and recent results are given below.
