Experimental and computational investigation of temperature effects on soot mechanisms [PDF]
Journal of the Serbian Chemical Society, 2014 Effects of initial ambient temperatures on combustion and soot emission characteristics of diesel fuel were investigated through experiment conducted in optical constant volume chamber and simulation using phenomenological soot model.

Enhanced soot particle ice nucleation ability induced by aggregate compaction and densification [PDF]
Atmospheric Chemistry and Physics, 2022 Soot particles, acting as ice nucleating particles (INPs), can contribute to cirrus cloud formation, which has an important influence on climate. Aviation activities emitting soot particles into the upper troposphere can potentially impact ice nucleation

Quantifying evolution of soot mixing state from transboundary transport of biomass burning emissions
iScience, 2023 Summary: Incomplete combustion of fossil fuels and biomass burning emit large amounts of soot particles into the troposphere. The condensation process is considered to influence the size (Dp) and mixing state of soot particles, which affects their solar ...

Numerical Simulation of Particle-Laden Flow and Soot Layer Formation in Porous Filter
Solids, 2022 So far, diesel particulate filters (DPFs) have been widely used to collect diesel particulates including soot in the exhaust after-treatment. However, as the soot is continuously collected in the porous filter, the exhaust pressure (pressure drop ...

Conditional moment closure modelling of soot formation in turbulent, non-premixed methane and propane flames [PDF]
, 2009 Presented are results obtained from the incorporation of a semi-empirical soot model into a first-order conditional moment closure (CMC) approach to modelling turbulent, non-premixed methane–air and propane–air flames.

Sooting turbulent jet flame: characterization and quantitative soot measurements [PDF]
Applied Physics B, 2011 Computational fluid dynamics (CFD) modelers require high-quality experimental data sets for validation of their numerical tools. Preferred features for numerical simulations of a sooting, turbulent test case flame are simplicity (no pilot flame), well-defined boundary conditions, and sufficient soot production.

On the Response of Nascent Soot Nanostructure and Oxidative Reactivity to Photoflash Exposure
Energies, 2017 Soot particles are a kind of major pollutant from fuel combustion. To enrich the understanding of soot, this work focuses on investigating detailed influences of instantaneous external irradiation (conventional photoflash exposure) on nanostructure as ...
