Effect of hydrogen addition on the laminar premixed combustion characteristics the main components of natural gas
TL;DR: In this paper, the effect of hydrogen addition on the combustion characteristics of natural gas was investigated with a ChemkinⅡ/premix code with the detailed chemical reaction mechanisms with the Soret effect taken into account in all the calculations.

A comparison between direct numerical simulation and experiment of the turbulent burning velocity-related statistics in a turbulent methane-air premixed jet flame at high Karlovitz number
TL;DR: In this article, a 3D direct numerical simulation (DNS) of an experimental turbulent premixed jet flame at high Karlovitz number was studied, and the results were comparable with other values reported for various experimental flames.

Weakly Bound Free Radicals in Combustion: “Prompt” Dissociation of Formyl Radicals and Its Effect on Laminar Flame Speeds
Nicole J. Labbe,Raghu Sivaramakrishnan,C. Franklin Goldsmith,Yuri Georgievskii,James A. Miller,Stephen J. Klippenstein +5 more
TL;DR: It is suggested that HCO prompt dissociation should be included when simulating flames of hydrocarbons and oxygenated molecules and that prompt dissociations of other weakly bound radicals may also impact combustion simulations.
Journal ArticleDOI
Detailed numerical simulation of transient mixing and combustion of premixed methane/air mixtures in a pre-chamber/main-chamber system relevant to internal combustion engines
TL;DR: In this article, a simplified prechamber/main-chamber system is investigated using direct numerical simulation (DNS) with detailed chemical kinetics, and the progress and topology of flame evolution, and mean burning velocity in the main chamber are analyzed in detail.

Measurements and calculations of formaldehyde concentrations in a methane/N2/air, non-premixed flame: Implications for heat release rate
Seth B. Dworkin,Andrew M. Schaffer,B.C. Connelly,Marshall B. Long,Mitchell D. Smooke,M.A. Puccio,B. McAndrew,J.H. Miller +7 more
TL;DR: In this paper, a non-sooting, lifted, methane/air, co-flowing, non-premixed flame has been studied experimentally and computationally, and the flame structure was computed by solving the fully elliptic governing equations.

Assessment of Chemical Markers for Heat-Release Rate Correlations in Laminar Premixed Flames
TL;DR: In this paper, the authors investigated the validity of corrections developed for methane to the combustion of other fuel classes (e.g., alcohols, unsaturated hydrocarbons, and aromatics), and proposed a methodological approach for the development of generic correlations.
