“…The terms on the right side are the rate of laser energy absorption by the aggregate, the soot sublimation, the rate of heat loss by conduction from the aggregate to the surrounding gas, and thermal radiation, respectively. The parameter N p represents the number of primary soot particles within the aggregate, d p is the primary soot particle diameter, ρ s and c s denote the soot particle density and specific heat, which are set to the values used by Liu et al (2006a), and T p and t are the laser-heated soot particle temperature and time, respectively. The variable E(m) in the first term on the right-hand side represents the refractive index function, and λ and q(t) are the excitation wavelength and pulsed laser temporal intensity, respectively.…”
