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.

Soot-PCF: Pore condensation and freezing framework for soot aggregates [PDF]
Atmospheric Chemistry and Physics, 2020 Abstract. How ice crystals form in the troposphere strongly affects cirrus cloud properties. Atmospheric ice formation is often initiated by aerosol particles that act as ice nucleating particles. The aerosol-cloud interactions of soot and associated feedbacks remain uncertain, in part because a coherent understanding of the ice nucleation mechanism ...

Stochastic Simulation of Soot Formation Evolution in Counterflow Diffusion Flames
Journal of Nanotechnology, 2018 Soot generally refers to carbonaceous particles formed during incomplete combustion of hydrocarbon fuels. A typical simulation of soot formation and evolution contains two parts: gas chemical kinetics, which models the chemical reaction from hydrocarbon ...

Soot Emission Analysis in Combustion of Biogas Diesel Dual Fuel Engine
Environmental Science and Sustainable Development, 2017 Soot emission in bio-gas diesel dual fuel engine has been analyzed by numerical simulation with 2-stape soot formation model of Magnussen. The result shows that soot formation mainly occurred in diffusion combustion phase of diesel pilot jet.

Effect of Thermodenuding on the Structure of Nascent Flame Soot Aggregates
Atmosphere, 2017 The optical properties (absorption and scattering) of soot particles depend on soot size and index of refraction, but also on the soot complex morphology and the internal mixing with materials that can condense on a freshly emitted (nascent) soot ...

Journal of Thermal Science and Technology, 2019 The full-spectrum k-distribution (FSK) method and Generalized Multiparticle Mie-solution (GMM) method are applied to study the influences of soot aggregation on the radiative heat transfer in homogeneous gas-soot mixtures. The radiative transfer equation
