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 ... -
Active fluidic control of a cylinder in a cross-flow using synthetic jet actuation
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)The objective of this body of work is to establish the effectiveness of a simple synthetic jet actuator in modifying the drag forces experienced by a cylinder in a cross flow. This is achieved through the production of a ... -
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 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 ... -
Cartilage extraceullular matrix-derived scaffolds for joint regeneration
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)The goal of this thesis was to address key limitations associated with autologous chondrocyte implantation (ACI) for articular cartilage regeneration, specifically the need for two hospital stays, cell culture and high ... -
Vertical Upflow Convective Boiling: Flow Regimes, Heat Transfer and EHD Augmentation
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)This work focuses on vertical upflow convective boiling in a tubular heat exchanger.

Towards 3D bioprinting of anatomically accurate, mechanically reinforced cartilage templates for biological joint resurfacing
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)Osteoarthritis (OA) is a pervasive disease worldwide which affects the articular cartilage and the underlying bone in synovial joints such as the knee. Currently, the only treatment for a severely degenerated knee joint ... -
Identification and Measurement of Variables Affecting Component Lifetime: A Case Study of Polymer Degradation in the Biopharmaceutical Industry
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)Modern maintenance methods are dependent upon understanding and monitoring component degradation; however, many industrial situations exist where monitoring is impossible, and component degradation mechanisms are not well ... -
3D Bioprinting of Developmentally Inspired Templates for Bone and Joint Regeneration
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)There is an urgent need to develop alternatives to synthetic joint prosthesis to promote the regeneration of diseased osteoarthritic joints. Cell based therapies have shown promise for repairing cartilage and bone; however, ... -
Predictions of Rotor Broadband Noise
