Abstract

This paper presents the differential mass scattering cross section [m2multiply by}g-1multiply by}sr-1] of various non-flaming and flaming fire generated smoke aerosols as well as nuisance aerosols created in the Fire Emulator/Detector Evaluator. These measurements have been determined for two linear polarizations and the scattering angle range of 5 to 135 at a wavelength of 632.8 nm. Small diameter particles have been separated from large particles using the forward scattering information. Discrimination of soot generated by flaming fuels from both smoke aerosols generated by non-flaming fires and nuisance aerosols is demonstrated by the ratio of forward (45 ) to backward scattering (135 ), the polarization ratio, and dependence on scattering parameter, q = (4π/λ)Sin(θ/2). Size distribution measurements were made to facilitate analysis of the light scattering results.
