- Abstract
- This paper presents the differential mass scattering cross section 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 deg to 135 deg 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 deg) to backward scattering (135 deg), the polarization ratio, and dependence on scattering parameter.
