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.
