Abstract EN
Soot generally refers to carbonaceous particles formed during incomplete combustion of hydrocarbon fuels.
A typical simulation of soot formation and evolution contains two parts: gas chemical kinetics, which models the chemical reaction from hydrocarbon fuels to soot precursors, that is, polycyclic aromatic hydrocarbons or PAHs, and soot dynamics, which models the soot formation from PAHs and evolution due to gas-soot and soot-soot interactions.
In this study, two detailed gas kinetic mechanisms (ABF and KM2) have been compared during the simulation (using the solver Chemkin II) of ethylene combustion in counterflow diffusion flames.
Subsequently, the operator splitting Monte Carlo method is used to simulate the soot dynamics.
Both the simulated data from the two mechanisms for gas and soot particles are compared with experimental data available in the literature.
It is found that both mechanisms predict similar profiles for the gas temperature and velocity, agreeing well with measurements.
However, KM2 mechanism provides much closer prediction compared to measurements for soot gas precursors.
Furthermore, KM2 also shows much better predictions for soot number density and volume fraction than ABF.
The effect of nozzle exit velocity on soot dynamics has also been investigated.
Higher nozzle exit velocity renders shorter residence time for soot particles, which reduces the soot number density and volume fraction accordingly.
