Assessment of the impact of widespread integration of compressed natural gas filling stations and biomethane injection on the gas network
Keogh, Niamh (NUI Galway, 2023-01-16)The research in this thesis has explored, investigated and analysed the integration of biomethane production and injection facilities and compressed natural gas (CNG) filling stations in to gas distribution networks, ... -
Comprehensive techno-econo-environmental modelling of renewable hydrogen supply chains
Gunawan, Tubagus Aryandi (NUI Galway, 2022-03-01)The research in this thesis has explored, investigated, and analysed renewable hydrogen supply chain opportunities and optimisation through techno-econo-environmental modelling. The modelling incorporates capital and ... -
Computational modelling of emissions from gas turbines: Ensuring experimental reliability and quantifying emissions uncertainty
Yousefian Najafabadi, Sajjad (NUI Galway, 2019-02-18)Global environmental concerns and the increasing amount of power generated using gas turbines have led to the development of dry low emission (DLE) combustion systems to minimize the NOx and CO pollutants. Improvements in ... -
Development of correlated and computational methods for predicting premixed turbulent flame speed
Burke, Eoin M. (NUI Galway, 2018-10-02)Turbulent flame speed is an important property within turbulent flames and an invaluable parameter for gas turbine combustor design. A major issue however is the difficulty in accurately predicting turbulent flame speed ... -
Experimental and numerical characterisation of materials for biomass co-firing
O'Hagan, Conor (2017-02-23)As Europe continues to decarbonize its electricity generation capacity, operators of thermal power plants face challenges to which they must adapt including increasingly transient operation and co-firing with biomass. This ... -
Experimental development and modelling of a novel auxiliary power unit for heavy trucks
Flannery, Barry (2017-09-26)This thesis identifies the key technical requirements for a heavy truck auxiliary power unit (APU) and explores a potential alternative technology for use in a next-generation APU that could eliminate key problems related ... -
Spatially explicit economic and environmental optimisation of bio-SNG production systems integration with the Irish gas network
Singlitico, Alessandro (NUI Galway, 2019-11-08)Biomass-derived synthetic natural gas (bio-SNG), produced from biomass through gasification and cleaning and conditioning of syngas, is an energy carrier compatible with the existing gas infrastructure and appliances, is ... -
Towards the automatic generation of zonal models from CFD simulations
Marzullo, Thibault (NUI Galway, 2020-04-14)This doctoral thesis presents a novel computational tool chain able to automatically extract zonal models from CFD simulations of the built environment in order to provide accurate and rapid predictions of indoor temperature ...
