A new technique for vortex methods in computational fluid dynamics
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2002)The random vortex method is a Lagrangian technique which involves solving the stream function-vorticity formulation of the Navier-Stokes equations. Discrete vortex particles, which are created at the surface to satisfy ... -
A practical framework for strategic noise mapping
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2008)Environmental noise is a major form of pollution and it is estimated that at least one quarter of the population of the EU suffer a reduced quality of life due to exposure to noise. To address the problem the European Union ... -
A stochastic model of damage accumulation in acrylic bone cement : application to failure modelling of cemented hip replacement
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)Acrylic bone cement, used to fixate several forms of orthopaedic joint replacement prosthesis, has a variable fatigue resistance arising mainly from porosity. It is argued that deterministic modelling assumptions of ... -
A study of heat transfer in forced convective drying with the application of laser-induced fluorescence thermometry
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Industrial drying is a highly energy-intensive process accounting for up to 25% of energy consumption in some developed countries. While there is a wide range of literature on the topic of drying, the majority of studies ... -
A study of the heat transfer processes and related flows of a synthetic jet impinging perpendicular to a heated surface
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)To maintain the development of modern technology and its thermally intensive processes, versatile methods of enhancing localised heat transfer are continually required. This need has resulted in an on-going drive to achieve ... -
A study of the role of oil additives in the failure of ball bearings
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2000)This thesis examines the influence that extreme pressure oil additives have in the failure of ball bearings. Additives are commonly used in lubricating oils to improve their properties. In recent years some sections of ... -
A validated computational fluid dynamics methodology for characterisation of fluid flow and heat transfer in unsteady jets
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)To improve reliability and avoid premature failure in electronic devices, more effective techniques must be used to dissipate the heat generated by devices. Thermal simulations can enable engineers to investigate and verify ... -
A validated shape optimization approach for maximizing the convective heat transfer from generic heat sink geometries
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Improving the effectiveness of heat transfer devices is one of the most challenging and determinant processes for industrial situations involving energy transformation. Thermal simulations can enable engineers to try and ... -
