Autoignition of ethanol in a rapid compression machine
(Elsevier, 2013-12-09)Ethanol is a renewable source of energy and significant attention has been directed to the development of a validated chemical kinetic mechanism for this fuel. The experimental data for the autoignition of ethanol in the ... -
Comparison of the performance of several recent syngas combustion mechanisms
(Elsevier ScienceDirect, 2015-01-22)A large set of experimental data was accumulated for syngas combustion: ignition studies in shock tubes (732 data points in 62 datasets) and in rapid compression machines (492/47), flame velocity determinations (2116/217) ... -
A detailed chemical kinetic modeling, ignition delay time and jet-stirred reactor study of methanol oxidation
(Elsevier, 2016-01-29)A shock tube (ST) and a rapid compression machine (RCM) have been used to measure new ignition delay times for methanol oxidation over a wide range of pressures (2-50 atm) and equivalence ratios (0.5, 1.0, and 2.0). These ... -
Experimental and kinetic modeling study of 3-Methyl-2-butenol (Prenol) oxidation
(American Chemical Society, 2021-08-19)Longer chain alcohols with 4–5 carbon atoms are attractive alternative fuels as they can be derived from biological sources and since their combustion leads to lower exhaust gas levels of NOx and soot compared to commercial ... -
Experimental and kinetic modeling study of the shock tube ignition of a large oxygenated fuel: tri-propylene glycol mono-methyl ether
(Elsevier, 2015-05-13)Tri-propylene glycol monomethyl ether (TPGME) is an important oxygenated fuel additive that can be used to reduce soot in diesel engines. However, a validated chemical kinetic model that incorporates the low- to high-temperature ... -
An experimental and modeling study of nitromethane + O2 + N2 ignition in a shock tube
(Elsevier, 2016-09-09)The ignition of nitromethane/O-2/N-2 mixtures was investigated via shock tube experiments in the temperature range 947-1333 K at reflected shock pressures near 8, 16 and 32 atm. The ignition was recorded as the intensity ... -
Influence of steam dilution on the ignition of hydrogen, syngas and natural gas blends at elevated pressures
(Elsevier ScienceDirect, 2014-11-10)This paper presents the influence of steam dilution on the autoignition behaviour of hydrogen, carbon monoxide, syngas, methane, and natural gas mixtures under gas turbine-relevant conditions. Rapid compression machine ... -
Modeling ignition of a heptane isomer: improved thermodynamics, reaction pathways, kinetics, and rate rule optimizations for 2-methylhexane
(American Chemical Society, 2016-03-21)Accurate chemical kinetic combustion models of lightly branched alkanes (e.g., 2-methylalkanes) are important to investigate the combustion behavior of real fuels. Improving the fidelity of existing kinetic models is a ... -
Optimization of a hydrogen combustion mechanism using both direct and indirect measurements
(Elsevier ScienceDirect, 2014-07-05)The Keromnes et al. (2013) mechanism for hydrogen combustion has been optimized using a large set of indirect experimental data, consisting of ignition measurements in shock tubes (566 datapoints in 43 datasets) and rapid ... -
Quantitative polymorph contaminant analysis in tablets using Raman and near infra-red spectroscopies
(2013)The detection and quantification of alternate polymorphs of active pharmaceutical ingredients (APIs), particularly at low concentrations is a key issue for the manufacture and analysis of solid-state formulations. Each ... -
Sulfamerazine: Understanding the influence of slip planes in the polymorphic phase transformation through X-ray crystallographic studies and ab initio lattice dynamics
(American Chemical Society, 2015-08-28)Understanding the polymorphism exhibited by organic active-pharmaceutical ingredients (APIs), in particular the relationships between crystal structure and the thermodynamics of polymorph stability, is vital for the ...
