A PAH growth mechanism and synergistic effect on PAH formation in counterflow diffusion flames

Y Wang, A Raj, SH Chung - Combustion and flame, 2013 - Elsevier
A reaction mechanism having molecular growth up to benzene for hydrocarbon fuels with
up to four carbon-atoms was extended to include the formation and growth of polycyclic …

A reaction mechanism for gasoline surrogate fuels for large polycyclic aromatic hydrocarbons

A Raj, IDC Prada, AA Amer, SH Chung - Combustion and Flame, 2012 - Elsevier
This work aims to develop a reaction mechanism for gasoline surrogate fuels (n-heptane, iso-octane
and toluene) with an emphasis on the formation of large polycyclic aromatic …

Soot modeling of counterflow diffusion flames of ethylene-based binary mixture fuels

Y Wang, A Raj, SH Chung - Combustion and Flame, 2015 - Elsevier

Towards a detailed soot model for internal combustion engines

S Mosbach, MS Celnik, A Raj, M Kraft, HR Zhang… - Combustion and …, 2009 - Elsevier
In this work, we present a detailed model for the formation of soot in internal combustion
engines describing not only bulk quantities such as soot mass, number density, volume fraction, …

A statistical approach to develop a detailed soot growth model using PAH characteristics

A Raj, M Celnik, R Shirley, M Sander, R Patterson… - Combustion and …, 2009 - Elsevier
A detailed PAH growth model is developed, which is solved using a kinetic Monte Carlo
algorithm. The model describes the structure and growth of planar PAH molecules, and is …

Structural effects on the oxidation of soot particles by O2: Experimental and theoretical study

A Raj, SY Yang, D Cha, R Tayouo, SH Chung - Combustion and Flame, 2013 - Elsevier
Soot particles are composed of polycyclic aromatic hydrocarbons (PAHs), which have either
planar or curved structures. The oxidation behaviors of soot particles differ depending on …
