TL;DR: The work at NUI Galway was supported by Saudi Aramco under the FUELCOM program as discussed by the authors, and the collaboration between NUIGalway and LRGP entered in the frame the COST Action CM1404.
Journal ArticleDOI
A Semi-Empirical Reaction Mechanism for n-Heptane Oxidation and Pyrolysis
TL;DR: In this paper, a semi-empirical mechanism for n-heptane oxidation and pyrolysis has been developed and validated against several independent data sets, including new flow reactor experiments.
Journal ArticleDOI
A comprehensive mechanism for methanol oxidation
TL;DR: In this article, a detailed chemical kinetic mechanism for methanol oxidation has been developed and validated against multiple experimental data sets, and the data are from static-reactor, flow-reactor, shock-tube, and laminar-flame experiments, and cover conditions of temperature from 633-2050 K, pressure from 0.26-20 atm, and equivalence ratio from 1.05-2.6.

Methods and apparatus for reducing gas turbine engine emissions
TL;DR: In this paper, a reverse flow can-type combustor is described, where each swirler and mixer in the array includes a primary and secondary fuel delivery system that can be independently controlled to produce low CO, UHC, and NOx emissions at design set point and at conditions other than design set-point.
Journal ArticleDOI
Challenges and Progress in Controlling Dynamics in Gas Turbine Combustors
TL;DR: In this article, the components of a combined analytical, experimental, and computational approach to understand and control combustion dynamics are developed for turbopropulsion engine combustors and industrial combustors.
