Soot emission from diesel combustion
MTZ worldwide, 2002At the Laboratory for Internal Combustion Engines (LVV) of the Swiss Federal Institute of Technology (ETH), soot formation and oxidation during the highly turbulent, unsteady combustion in a DI diesel engine has been investigated. In particular, the aim was to examine the influence of fluid dynamic processes (injection pressure) and thermodynamic ...

Monitoring the Soot Emissions of Passing Cars
Environmental Science & Technology, 2006We report on the first application of a novel fast on-road sensing method for measurement of particulate emissions of individual passing passenger cars. The studywas motivated by the shift of interest from gases to particles in connection with strong adverse health effects. The results correspond very much to findings by Beaton et al.

Sooting flame thermometry using emission/absorption tomography
Applied Optics, 1990A sooting flame temperature measurement technique has been demonstrated based on emission-absorption tomography. The approach applies the algorithms of Fourier transform tomography to deconvolve local soot absorption coefficient and Planck function (temperature) from sets of parallel line-of-sight measurements.

Soot pyrometry using modulated absorption/emission
Combustion and Flame, 2001Abstract A new method of optical pyrometry for sooting flames has been developed that combines absorption and emission measurements at the same wavelength, reducing the uncertainty in measured soot temperature when compared to commonly used two-color emission pyrometry.

The emissivities of flame soot dispersions
Combustion and Flame, 1971The Mie theory has been applied to predict the emissivities of soot dispersions in luminous flames. Significant variations in the optical constants of gas- and oil-flame soots exist in the literature, and their effects on the emissivities of otherwise similar soot dispersions have been determined.

Experimental Thermal and Fluid Science, 2022
Abstract A simple and cost-effective temperature and soot volume fraction measurement technique that does not rely on spectral or absolute irradiance calibration is developed. The technique is based on a three-sensor CMOS camera, where the broadband sensitivity of RGB sensors were narrowed down to representative wavelengths using a tri-bandpass ...

Modeling Soot Emissions in Combustion Systems
1981A comprehensive model for the characterization of the combustion kinetics of hydrocarbon fuels is described. The model framework is based upon the quasi-global concept and extensions appropriate for fuel rich oxidation. Soot formation and consumption processes are considered as an integral part of the model, and pyrolysis, partial oxidation, NOx ...
