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

Effect of Precursors and Radiation on Soot Formation in Turbulent Diffusion Flame [PDF]
Fuel, 2015, 2021 Soot formation in Delft flame III, a pilot stabilized turbulent diffusion flame burning natural gas/air, is investigated using ANSYS FLUENT by considering two different approaches for soot inception. In the first approach soot inception is based on the formation rate of acetylene, while the second approach considers the formation rate of two and three ...

Numerical Investigation of Soot Formation in Turbulent Diffusion Flame with Strong Turbulence Chemistry Interaction [PDF]
Journal of Thermal Science and Engineering Applications 2016, 2021 The present work is aimed at examining the ability of different models in predicting soot formation in Delft flame III, which is a non-premixed pilot stabilized natural gas flame. The turbulence-chemistry interactions are modeled using a laminar steady flamelet model (SLFM).

Morphology and Electronic Properties of Incipient Soot by Scanning Tunneling Microscopy and Spectroscopy [PDF]
Combustion and Flame 243 (2022) 111980, 2022 Soot nucleation is one of the most complex and debated steps of the soot formation process in combustion. In this work, we used scanning tunneling microscopy (STM) and spectroscopy (STS) to probe morphological and electronic properties of incipient soot particles formed right behind the flame front of a lightly sooting laminar premixed flame of ...

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 ...

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 ...

Gas and soot formed in the dimethoxymethane pyrolysis. Soot characterization [PDF]
Fuel Processing Technology, 2018 The many simultaneous processes occurring within in a diesel engine make difficult a thorough understanding of the mechanisms responsible for reduction of soot and/or NOX when an oxygenated compound is added to diesel fuel. Thus, in order to explore the use of oxygenated compounds as biofuels/additives, it is interesting to study their conversion under

Assessment of Soot Formation Models in Lifted Ethylene/Air Turbulent Diffusion Flame [PDF]
Thermal Science and Engineering Progress, 2017, 2021 In the present study, soot formation in the turbulent lifted diffusion flame, consisting of ethylene-air is numerically investigated using three different soot modeling approaches and is comprehensively reported. For turbulence-chemistry interaction, Flamelet generated manifold (FGM) model is used.
