Department of Mechanical and Manufacturing Engineering, 2013)The application of impinging jets for cooling purposes is an ongoing search for greater levels of heat dissipation in a world where manufacturing processes are getting more advanced and electrical systems are becoming ... -
Hydrodynamics and heat transfer of laminar pulsating flow in a rectangular channel
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)The exploitation of flow pulsation is a potentially useful technique for enhanced cooling in single-phase cooling systems. This thesis contains parametric analyses of the hydrodynamics and heat transfer of a laminar ... -
Hypothesis testing of glenoid component innovation in total shoulder arthroplasty
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)A glenoid component with reliable long-term performance does not exist for total shoulder arthroplasty. Poor glenoid component durability may be explained by the huge variability that exists at the shoulder 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 ... -
