An autoignition study of hydrogen and natural gas mixtures under gas turbine relevant conditions in a rapid compression machine
Donohoe, Nicola (2013-11-14)This study presents an experimental and modelling investigation of the ignition of hydrogen and natural gas mixtures. These mixtures were chosen due to their relevancy to the gas turbine industry. A detailed chemical ... -
A chemical kinetic computational toolkit for computational modelling and estimation of fuel thermodynamic properties
Sánchez Martínez, Sergio Enrique (NUI Galway, 2023-03-27)It is undeniable that, due to human activity, global warming is one of the most challenging environmental issues of our time. It is well known that the main source of greenhouse gases (GHG) is due to the burning of ... -
The combustion of fuel reference compounds in laboratory-scale reactors and flames
Banyon, Colin (NUI Galway, 2018-05-14)Internal combustion engines that rely heavily on fuel oxidation chemical kinetics, rather than external ignition sources, promise the simultaneous improvement of thermodynamic efficiencies and reduction of pollutant emissions ... -
Development of a Chemical Kinetic Mechanism for Small Hydrocarbons
Burke, Sinéad M. (2014-01-07)A detailed chemical kinetic mechanism has been developed to describe the oxidation of small hydrocarbon and oxygenated hydrocarbon species. In order to understand the oxidation of large hydrocarbon and oxygenated hydrocarbon ... -
The development of reliable chemical kinetic mechanisms to describe the oxidation of natural gas blends containing C1– C7 n-alkanes and the effects of NOx on natural gas oxidation at practical combustor relevant conditions
Mohamed, Ahmed Abdelsabor Mahmoud (NUI Galway, 2022-03-01)The use of natural gas (NG) for transportation and heavy-duty power generation applications has led to an increase in demand for conventional and non-conventional NG sources. Moreover, techniques such as exhaust gas ... -
Experimental and modelling studies of natural gas and gasoline surrogate blends
Patel, Vaibhav (NUI Galway, 2023-03-09)Combustors rely heavily on fossil and/or bio-derived fuels that all produce significant quantities of greenhouse gas (GHG) emissions. Hence, the successful development of advanced combustors requires predictive chemical ... -
An experimental and modelling study of selected oxygenated biofuels
Burke, Ultan (2014-10-13)Detailed chemical kinetic models are useful tools for the development of more efficient combustion systems. These models require validation of the elementary kinetics used in order for them to be accurate and reliable. ... -
An experimental and modelling study of the combustion of oxygenated hydrocarbons
Gillespie, Fiona Rita (2014-03-19)A chemical kinetic mechanism for the combustion of acetone has been developed and compared with a range of experimental data from the literature and with species concentration profiles measured in this study in the Princeton ... -
An Experimental and Modelling Study of the Oxidation of n-Propylbenzene Over a Wide Range of Temperatures and Pressures and its Comparison with n-Butylbenzene
Darcy, Daniel (2013-04-05)This study presents an experimental and modeling investigation of the ignition of n-propylbenzene and a mixture of n-propylbenzene and n-heptane. This mixture was chosen to represent a surrogate for n-decylbenzene a common ... -
Experimental studies of simple hydrocarbons in a shock tube
Sakleshpur Nagaraja, Shashank (NUI Galway, 2020-09-24)Chemical kinetic models are needed to simulate fuel chemistry in combustion devices and to aid in the development of new designs to reduce harmful emissions and maximize combustor performance. However, these models need ... -
A High Pressure Shock Tube and Rapid Compression Machine Study of n-Butylcyclohexane and its Mixtures with n-Heptane
Conroy, Christine (2013-07-01)This study presents a high pressure experimental and modelling investigation on the ignition of n-butylcyclohexane and its mixtures with n-heptane. Mixtures were chosen to represent a surrogate for n-decylcyclohexane, a ... -
