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 ...

Numerical investigation of soot mass concentration in compression ignition diesel engine
Journal of Mechanical Engineering and Sciences, 2016 Soot particles, carbon monoxide, oxides of nitrogen, oxides of sulphur, and hydrocarbon are the emissions produced from diesel engine combustion. Those emissions species are undesirable since they give detrimental impacts to the atmosphere and human ...
