“…Considering the very dynamic nature of the biomass burning process, it was very important to monitor air emission on a frequent basis and over the complete duration of the process starting from ignition and completed at the entire extinction of smoke particles. Such capability is offered by the diffusion aerosol spectrometer (DAS) (Model 2702M, Aeronanotech, Moscow, Russia) [29]. The instrument is capable of monitoring airborne particles with a time resolution of one second in two size ranges (3 nm-200 nm and 200 nm-10,000 nm) in parallel, combining condensation particle counting for smaller sizes of <200 nm and light scattering for particles larger than 200 nm.…”

Particle size distribution in biomass smoke was observed for different burning phases, including flaming and smouldering, during the combustion of nine common Australian vegetation representatives. Smoke particles generated during the smouldering phase of combustions were found to be coarser as compared to flaming aerosols for all hard species. In contrast, for leafy species, this trend was inversed. In addition, the combustion process was investigated over the entire duration of burning by acquiring data with one second time resolution for all nine species. Particles were separately characterised in two categories: fine particles with dominating diffusion properties measurable with diffusion-based instruments (Dp < 200 nm), and coarse particles with dominating inertia (Dp > 200 nm). It was found that fine particles contribute to more than 90 percent of the total fresh smoke particles for all investigated species.

In this paper, an iterative model is constructed for the formation of a sediment of inertial aerosol particles on the surface of a cylindrical fiber, taking into account its effect on the gas flow and further settling of the particles. Parametric calculations are carried out for various values of the porosity of a number of fibers and the Stokes number, which determines the inertia of the particles. The shape of the sediment varies depending on the particle size. For strongly inertial particles, the thickness of the layer of settled particles is close to uniform. For weakly inertial particles with a small porosity of a number of fibers, a nonuniform distribution of the thickness of the deposited layer along the streamlined surface is observed.
