Counterflow Spray Combustion Modeling with Detailed Transport and Detailed Chemistry

Combustion and Flame, 1998
Abstract Structures of axisymmetric and planar counterflow spray flames are investigated by means of numerical integrations. The study emphasizes the effects of both detailed transport and detailed chemistry on flame structure and extinction conditions.

Detailed Kinetic Modeling of Autoignition Chemistry

SAE Technical Paper Series, 1987
<div class="htmlview paragraph">The development of detailed chemical kinetic reaction mechanisms for analysis of autoignition and knocking of hydrocarbon fuels is described. In particular, kinetic processes of concern for the oxidation of complex hydrocarbon fuel molecules are emphasized.

Emission Prediction with Detailed Chemistry

SAE Technical Paper Series, 2019
<div class="section abstract"><div class="htmlview paragraph">Numerical modeling of engine combustion products requires detailed chemistry and therefore large computational resources and time. This becomes a constraint when engine optimization at system level is desired. In this paper, a 1D modeling approach is proposed for fast computation

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.

Detailed and reduced chemistry for methanol ignition

Combustion and Flame, 2011
Abstract Simplified chemical-kinetic mechanisms are sought that can provide agreement with measured shock-tube autoignition times and counterflow critical ignition conditions for methanol (CH 3 OH) oxidation. Existing detailed chemistry over-predicts measured counterflow ignition temperatures by 100 K or more. It was found that the elementary step CH

Dual timestepping methods for detailed combustion chemistry

Combustion Theory and Modelling, 2016
In this work, we develop and study several dual time integration methods for the solution of stiff, explosive differential equations governing combustion chemistry. Dual time integration is an implicit method wherein the sub-iteration process of each timestep is performed as a steady-state integration process, rather than the commonly used Newton ...

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.

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 ...
