Wide Range Performance Measurement and Low-Fidelity Modelling of Turbocharger Turbines for Optimising Powertrain Efficiency
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2024)Turbochargers have been widely used for many years and have made remarkable contributions in reducing the vehicle emissions by reducing the engine size while maintaining the same power output. They are also needed in designs ... -
Application of the Theory of Critical Distances to As-Built Selective Laser Melted Ti-6Al-4V
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2024)Metal additive manufacturing (AM) techniques such as selective laser melting (SLM) have become an increasingly present feature of new and novel manufacturing methods in recent years. This is owed to further technological ... -
Solid-state Deposition of Bulk Metallic Glass and High-entropy Alloy via Cold Spray
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2024)Metallic glasses (MGs) and high-entropy alloys (HEAs) are both emerging multi-component alloys with unique microstructures and extraordinary properties. Cold spray, as a burgeoning solid-state material deposition process, ... -
Analysing the effects of 3D printing defects and surface roughness on the properties of acoustic materials
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)The principal aim of the research reported in this thesis was to investigate the influence of additive manufacturing on the acoustic performance of 3D printed periodic materials. First, a benchmark material design was ... -
AN INVESTIGATION OF HEAT TRANSFER ENHANCEMENT DUE TO PULSED FLOW IN MINICHANNELS
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)The development of current and next generation high performance electronic devices has led to smaller components in more densely packed spaces. The increasing power levels has resulted in ever-increasing heat flux densities ...
