In order to investigate the effect of DME mixing on number density and size of soot particle, DME has been mixed in counterflow pure ethylene diffusion flame with the mixture ratios 5 %, 14 % and 30 %. A laser extinction/scattering technique has been adopted to measure the volume fraction, number density, and size of soot particles. The experimental results showed that the soot concentration of mixture flames with the mixture ratios 5 % and 14 % produces soot more, even though that of 30 % was decreased. Numerical results showed that the importance of methyl radicals on the formation of propargyl was emphasized and the propargyl recombination to benzene could lead to the increase in the number density for the cases exhibiting the synergistic effect.

In order to investigate the effect of benzene (C?H?) and toluene (C?H?) mixing on polycyclic aromatic hydrocarbon (PAH) and soot formation, benzene and toluene have been mixed in counterflow pure ethylene diffusion flame. Laser induced incandescence (LII) and laser induced fluorescence (LIF) techniques have been adopted to measure relative concentrations of soot volume fraction and polycyclic aromatic hydrocarbon (PAH) concentration, respectively. The experimental results showed that the mixing of liquid fuels in ethylene diffusion flame produces more PAHs and soot than that of pure ethylene diffusion flame. Especially, LII signal of 20% toluene flame increased about 3.5 times more than that of pure ethylene diffusion flame. It is considered that methyl (CH₃) radical generated by the initial pyrolysis of benzene can be contributed to the enhancement of PAH and soot formation, through the formation of propargyl (C₃H₃) radical.
