Abstract The snow physical parameters are closely related to the sizes, shapes, and chemical composition of light‐absorbing particles (LAPs). By utilizing a computer‐controlled scanning electron microscope software called IntelliSEM‐EPAS TM , we first report measured size‐resolved concentration soot, dust, fly ash in fresh (wet) aged (dry deposition) samples collected at an industrial city Chin...

The formation of polycyclic aromatic hydrocarbons (PAH) and soot has become one of the central themes of research activities in the area of combustion and pyrolysis of hydrocarbon fuels. The interest in the subject stems mostly from environmental concerns on pollutant emission from combustion devices. The research activities span experimental, theoretical, and computational efforts and cover a ...

The current study presents novel experimental data on soot particle size distributions (PSDs) with mobility diameters in the range 4≤Dm[nm]≤230 obtained from four premixed turbulent ethylene-air flames crossing inception limit. are stabilised against hot combustion products nitrogen diluted hydrogen a back-to-burnt (or fresh-to-burnt) opposed jet configuration. burner features fractal grid gene...

An experimental study of the interaction of a planar diffusion flame with a line vortex is presented. A planar diffusion flame is established between two coflowing, equal velocity streams of acetylene diluted with nitrogen and air. A line vortex is generated on demand by momentarily pulsing one of the flow streams by way of electromagnetic actuation of a piston in the flow apparatus. The flame–...
