Light Extinction Characteristics of Soot Particle in Hydrocarbon Inverse Diffusion Flames.

역 확산화염 내 매연입자에 의한 광소멸 특성 연구

Light extinction characteristics of soot particles in ethylene and propane inverse diffusion flames have been experimentally investigated. The measured data suggested that the refractive index of soot particles varies with light wavelength due to PAH contents existing during the soot growth process. The results showed that the scattering effect is less important as the size of secondary particles rarely affects the optical properties of the soot even when the size is large enough to deviate from Rayleigh assumptions.
