Soot particle size distribution reconstruction in a turbulent sooting flame with the split-based extended quadrature method of moments [PDF]
Physics of Fluids 34, 075121 (2022), 2022 The Method of Moments (MOM) has largely been applied to investigate sooting laminar and turbulent flames. However, the classical MOM is not able to characterize a continuous particle size distribution (PSD). Without access to information on the PSD, it is difficult to accurately take into account particle oxidation, which is crucial for shrinking and ...

Experimental and numerical study on the effect of oxymethylene ether-3 (OME3) on soot particle formation [PDF]
Fuel Volume 286, Part 1, 2021, 119353, ISSN 0016-2361, 2021 The reduction and control of particulate matter generated by fossil fuel combustion are among the main issues for actual and future combustion devices due to the increasingly stringent emission regulations. Recently, various fuels have been investigated as a potential substitute or additive for diesel and gasoline. This work focuses on how oxymethylene

Soot-figures on Ceilings [PDF]
Nature, 1893 MAY I suggest a distinct, if not an alternative cause for Prof. E. B. Poulton's soot figures in NATURE, April 27th? The ceiling plaster is very porous, except where it is in contact with the joists, etc. At such points very little deposit occurs compared with the spaces where the hot air is vigorously diffusing through into the cold space above.

Soot formation characteristics in hybrid pyrolysis of zero-carbon fuel ammonia and ethylene mixtures
Frontiers in Energy Research, 2022 As soot particles from incomplete combustion of fossil fuels pose a great threat to human health, the development of low-carbon or zero-carbon alternative fuels is essential to mitigate climate change. An experimental and numerical study on the pyrolysis

Determination of the Soot Mass by Conductometric Soot Sensors
Procedia Engineering, 2014 AbstractSoot sensors are required for on-board diagnostics (OBD) of automotive diesel particulate filters (DPF) to detect filter failures. If installed upstream of a DPF, the “engine-out” soot emissions can be determined by conductometric soot sensors.
