An Experimental Study on the Particle Concentration and Size Distribution of Smoke Generated by Flaming N-Heptane

Abstract:

The particles of smoke generated by flaming n-heptane was measured by Fast Particulate Spectrometer (DMS500), and the particle number concentration and size distribution were recorded and analyzed for investigating the smoke dynamic characteristics. The experimental results indicated that the particle number concentrations of buoyant plume above the flame approximately decrease with the height. At the center of ceiling, there is an approximate linear relationship between the particle number concentration and heat release rate. The count median diameter (CMD) varies with time and the change rate of CMD varies with particle concentration. In these experiments, the CMD is a constant in a few minutes after burning extinction.
