✦ Synopsis


The evolution of the size distribution in a normal and in a ferrocene (Fe(C 5 H 5 ) 2 )-doped laminar diffusion flame is measured with a scanning mobility particle sizer. Measurements with a low-pressure impactor and a differential mobility analyzer allow the determination of the density () and the fractal-like dimension (d f ) of particles sampled from a laminar diffusion flame. Various fuels are used and in the case of CH 4 , the flame is doped with ferrocene. In all cases the particle densities are low, typically below 700 kg/m 3 . The data acquired from the doped flame support previous studies with ferrocene and enable us to propose a further refinement.
