Uncertainty quantification of reaction mechanisms accounting for correlations introduced by rate rules and fitted Arrhenius parameters
TL;DR: In this article, the authors studied correlations among uncertain Arrhenius rate parameters in a chemical model for hydrocarbon fuel-air combustion and examined the role of correlations, and considering both accuracy and computational efficiency.

Structure of n-heptane/air triple flames in partially-premixed mixing layers
TL;DR: In this article, a detailed numerical analysis of an n-heptane/air edge flame is presented, where the equations of a low-Mach number reacting flow are solved in a two-dimensional domain using detailed models for species transport and chemical reactions.

Analysis of methane–air edge flame structure
TL;DR: In this paper, the structure of a methane-air edge flame stabilized against an incoming mixing layer is computed using detailed chemical kinetics, and the analysis is based on computational singular perturbation theory.

TL;DR: In this article, an automated procedure has been developed to generate simplified skeletal reaction mechanisms for the combustion of n-heptane/air mixtures at equivalence ratios between 0.5 and 2.0 and different pressures.

TL;DR: In this paper, a methane-air edge flame was computed against an incoming flow mixing layer, using detailed methane-aer chemistry. But the edge flame structure changes with downstream distance, tending to a classical diffusion flame structure and the dominant reaction flux contributions in each pathway.
