Cometary gas and plasma flow with detailed chemistry
Computer Physics Communications, 1988Abstract This paper describes recent hydrodynamic and magnetohydrodynamic (MHD) simulations for the gas and plasma flow around a comet with detailed photo and chemical reaction network of 59 neutral and 76 ionized chemical species. The method allows for a separate energy balance of the electrons, separate flow of neutral gas, fast neutral atomic and ...

Detailed modeling of n-butane autoignition chemistry
Combustion and Flame, 1994Abstract Two versions of a detailed chemical kinetic model of n-butane autoignition are proposed. The key distinctions between the versions are the exclusion (Model I) or inclusion (Model II) of the direct abstraction or apparently bimolecular path of the reaction HO2 + HO2 → H2O2 + O2, and the selection of rate parameters for the reaction C2H5 + O2 →

Detailed Chemistry Simulations of a Trapped Vortex Combustor
Volume 1: Turbo Expo 2003, 2003Steady simulations of a Trapped Vortex Combustor are performed with the Strained Laminar Flamelet model, the Eddy Dissipation Concept (EDC) model and the Composition PDF Transport model using an accurate 19 species Augmented Reduced Mechanism. CO predictions are reasonable, although the EDC model over-predicts CO since the reaction time in the fine ...

Detailed and reduced chemistry for hydrogen autoignition
Journal of Loss Prevention in the Process Industries, 2008Abstract Reaction-rate parameters are given for the detailed chemistry of gas-phase hydrogen combustion, involving 21 reversible elementary steps. It is indicated that, when attention is restricted to specific combustion processes and particular conditions of interest, fewer elementary steps are needed.

Implementation of Detailed Chemistry Mechanisms in Engine Simulations
Volume 2: Emissions Control Systems; Instrumentation, Controls, and Hybrids; Numerical Simulation; Engine Design and Mechanical Development, 2017The stiffness of large chemistry mechanisms has been proved to be a major hurdle towards predictive engine simulations. As a result, detailed chemistry mechanisms with a few thousand species need to be reduced based on target conditions so that they can be accommodated within the available computational resources.

A LES Simulation of a CH4/Air Microcombustor with Detailed Chemistry
Combustion Science and Technology, 2011The authors compare numerical simulations and experiments carried out on a swirling methane/air cylindrical microcombustor with diameter and height 0.006 m and 0.009 m, respectively. They extend previous work, using LES and Flamelet methodology; here the EDC finite rate model and the GRIMech 1.2 (32 species and 177 reactions) mechanism are used.
