Kinetic modeling of soot formation in premixed burner-stabilized stagnation ethylene flames at heavily sooting condition [PDF]

open access: yes, 2018
A detailed kinetic mechanism of soot formation and oxidation is revised and extended to include temperature-dependent collision efficiencies. The collision efficiency for various particle size is studied and compared with experimental data and molecular ...

Effect of H2/CO addition on soot formation in ethylene diffusion flame

open access: yesFrontiers in Energy Research
Coupling the San Diego gas phase reaction mechanism and the Moss Brookes soot model using FLUENT14.0 software, the effect of adding H2/CO on the fuel side on soot formation in an ethylene/air laminar diffusion flame was studied.

Fuel property effects in stirred combustors [PDF]

open access: yes, 1980
Soot formation in strongly backmixed combustion was investigated using the jet-stirred combustor (JSC). This device provided a combustion volume in which temperature and combustion were uniform.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Visualization of the soot formation process in the volatile flame of single coal particle using 10-kHz PAHs-PLIF, LII and LIS

open access: yesNihon Kikai Gakkai ronbunshu, 2021
Soot formation process during coal combustion is one of a key phenomenon to achieve a high-performance furnace. This is because the thermal radiation of soot influences the temperature distribution and the heat transfer process in the furnaces.

Soot formation in a turbulent swirling flow [PDF]

open access: yes, 1977
The qualitative understanding of soot formation in simple models of gas turbine primary-zone combustors is summarized. Soot formation in flame radiation and air pollution was investigated.

Soot volume fraction profiling of asymmetric diffusion flames through tomographic imaging [PDF]

open access: yes, 2014
This paper presents the 3-D (three-dimensional) reconstruction of soot volume fraction of diffusion flames based on tomographic imaging and image processing techniques.

Reactive Laser Additive Manufacturing of Hierarchically Structured Aerogels

open access: yesAdvanced Materials, EarlyView.
Reactive laser additive manufacturing transforms printing into a chemically active synthesis step. Salt‐enabled transient reaction environments drive in situ formation of hierarchically structured graphitic aerogels with microtubular and nanoscale features in seconds.

Investigation of ethanol blending on soot particle evolution in counterflow diffusion flames of a gasoline surrogate

open access: yesApplications in Energy and Combustion Science
Across all transport sectors, there is an increasing recognition of the importance of reducing not only CO2 emissions but also other climate-impacting pollutants, such as soot particulate matter.

Parametric studies of contrail ice particle formation in jet regime using microphysical parcel modeling [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
Condensation trails (contrails) formed from water vapor emissions behind aircraft engines are the most uncertain components of the aviation impacts on climate change.
