A novel soot concentration field estimator applied to sooting ethylene/air laminar flames [PDF]
Engineering Applications of Computational Fluid Mechanics, 2019 Soot formation modeling, when incorporated into computational fluid dynamics of industrial devices, can be numerically prohibitive. Nonetheless, there remains a significant push to predict soot formation, so as to aid in environmentally sustainable ...

Measurement of Soot Concentration in Turbulent Diffusion Flames
JSME international journal. Ser. 2, Fluids engineering, heat transfer, power, combustion, thermophysical properties, 1987 Soot, total hydrocarbon, oxygen, and temperature in turbulent diffusion flames and partially premixed turbulent diffusion flames of C3H8 and C2H2 were measured to study the soot formation process in flames. Further, to study the effect of fuel properties on soot formation, the soot concentrations in CH2, C3H6, C3H8, C2H4 and C2H2 flams were also ...

Impacts of oxygenated compounds concentration on sooting propensities and soot oxidative reactivity: Application to Diesel and Biodiesel surrogates [PDF]
Fuel, 2017 The aim of this paper is to evaluate the effect of the oxygenated compounds concentration on sooting propensities of Diesel and Biodiesel surrogates and to investigate the oxidative reactivity of soot obtained by combustion of these surrogates using an atmospheric axisymmetric co-flow diffusion flame burner.

Formation of Soot in Oxygen-Enriched Turbulent Propane Flames at the Technical Scale [PDF]
Energies, 2020 Soot is an important component for heat transfer in combustion processes. However, it is also a harmful pollutant for humans, and strict emissions legislation motivates research on how to control soot formation and release. The formation of soot is known

The concentration of soot as a factor of change in the air quality [PDF]
Praxis Medica, 2016 Introduction: Soot usually occurs as a result of incomplete combustion of fuels containing carbon (fossil fuels - wood, coal). Air pollution is one of the most serious environmental threats to the urban population, which has harmful effects on human ...

Investigation of soot formation in pressurized swirl flames by laser measurements of temperature, flame structures and soot concentrations [PDF]
Proceedings of the Combustion Institute, 2015 Abstract Soot formation and oxidation were investigated in swirl flames operated with ethylene/air at elevated pressure in a gas turbine model combustor with optical access. Coherent anti-Stokes Raman scattering was used for temperature measurements, laser-induced incandescence for soot concentration and laser-induced fluorescence for the ...
