Investigation on the effect of fractal soot aggregation on radiative transfer in homogeneous gas-soot mixture using full-spectrum k-distribution method

open access: yesJournal of Thermal Science and Technology, 2019
The full-spectrum k-distribution (FSK) method and Generalized Multiparticle Mie-solution (GMM) method are applied to study the influences of soot aggregation on the radiative heat transfer in homogeneous gas-soot mixtures. The radiative transfer equation

Modelling of soot formation in laminar diffusion flames using a comprehensive CFD-PBE model with detailed gas-phase chemistry [PDF]

open access: yes, 2016
A discretised population balance equation (PBE) is coupled with an in-house computational fluid dynamics (CFD) code in order to model soot formation in laminar diffusion flames. The unsteady Navier–Stokes, species and enthalpy transport equations and the

Effects of dielectric-barrier-discharge plasma on soot and NOx in diffusion flame

open access: yesJournal of Thermal Science and Technology, 2022
In this study, we experimentally investigated soot and NOx in a diffusion flame on a coaxial burner. By applying a dielectric-barrier-discharge (DBD) plasma, we tried to reduce these emissions.

Classification of contaminants in diesel engine oils

open access: yesВестник СибАДИ, 2022
Introduction. The deterioration of engine oil in an internal combustion engine (ICE) is directly related to the ingress of various pollutants into the crankcase. Depending on the type of contamination, the type of sediment on engine part surfaces varies.
