    Di Bari, Sergio (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    In the present work the hydrodynamics of adiabatic gas bubble growth from a submerged orifice is investigated with the view of elucidating the interdependence of the bubble shape and the pressure field during growth and ...
  • Bubble impingement and the mechanisms of heat transfer enhancement 

    Donoghue, David B (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
    Fluid agitation and mixing ensuing from two phase flow has an important role to play within two phase flow heat exchangers, which are at the forefront of energy conversion. Within these environments, vapour bubbles may ...
  • Bubble-induced Marangoni convection 

    O'Shaughnessy, Séamus (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Thermal Marangoni convection about a 1mm radius air bubble situated under a heated wall of constant temperature immersed in a silicone oil layer (Pr = 220) of constant depth 5mm was experimentally investigated using a flow ...
  • Cartilage extraceullular matrix-derived scaffolds for joint regeneration 

    Vazão de Almeida, Henrique Martiniano (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 ...
  • Case study of the Home Energy Saving Scheme : a multidisciplinary approach 

    Byrne, Amiee Jennifer (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
    The EU has set itself the objective of achieving 20% primary energy savings by 2020. Because of the relatively recent move towards sustainability, there is a limited understanding of how effective related policies and ...
  • Characterisation and modelling of electro-pneumatic production systems 

    Harris, Paul (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Compressed air is a widely employed energy source in modern manufacturing, accounting for a large percentage of plant electrical energy usage. However, the energy efficiency of such systems can be particularly low. Accurate ...
  • Characterisation and Reduction of Aircraft Landing Gear Noise 

    NERI, ELEONORA (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2017)
    Aircraft noise has become an important concern in aviation design as it has a negative impact on the health of people living in the vicinity of airports. The total noise of an aircraft is generated by the engines and by ...

  • Composition and mechanical properties of osteoarthritic subchondral trabecular tibial bone 

    Gleeson, John Patrick (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    Osteoarthritis is a disease that has been characterised historically by the focal destruction of cartilaginous tissue and hence, is defined as such. However, recent investigations have brought this pathology into contention. ...
  • Computational and experimental investigation of bone cell response to mechanical stimuli 

    McGarry, James Gerard (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2006)
