A detailed DSMC surface chemistry model

AIP Conference Proceedings, 2014
This work is aimed at development of detailed molecular surface chemistry models for DSMC method, their implementation into the SMILE++ software system, verification and validation. An approach to construction of DSMC suface chemistry models based on macroscopic reaction rate data was proposed.

A LES Simulation of a CH4/Air Microcombustor with Detailed Chemistry

Combustion Science and Technology, 2011
The 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.

Physical Chemistry of Bile

Ultrasound Quarterly, 2017
AbstractDespite the overwhelming prevalence of cholelithiasis, many health care professionals are not familiar with the basic pathophysiology of gallstone formation. This article provides an overview of the biochemical pathways related to bile, with a focus on the physical chemistry of bile.

Cometary gas and plasma flow with detailed chemistry

Computer Physics Communications, 1988
Abstract 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 Chemistry Simulations of a Trapped Vortex Combustor

Volume 1: Turbo Expo 2003, 2003
Steady 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, 2008
Abstract 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.

Numerical Investigation of the PDRE Performance with Detailed Chemistry

42nd AIAA Aerospace Sciences Meeting and Exhibit, 2004
Performance analysis of the Pulse Detonation Rocket Engine (PDRE) is numerically conducted focusing on partially filled system. Initial explosives, inexplosive gas species, tube fill fraction, and equivalence ratio are chosen as parameters to clarify their effects on the performance of PDRE.

Implementation of Detailed Chemistry Mechanisms in Engine Simulations

Volume 2: Emissions Control Systems; Instrumentation, Controls, and Hybrids; Numerical Simulation; Engine Design and Mechanical Development, 2017
The 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.

Assumed PDF Modeling with Detailed Chemistry

2002
Turbulent fluctuations exert a significant influence on chemical production rates. If finite-rate chemistry is employed the use of probability density functions (pdf) allows to account for turbulence chemistry interaction. In this paper an assumed pdf approach incorporates the effects of temperature and species fluctuations on chemical reaction rates ...
