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 ... -
Process, precedent, and community : new learning environments for engineering design
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)Project-based design courses are an increasingly conunon component of engineering education. Most engineering schools have traditionally emphasized the analytical and scientific aspects of the discipline, and an increase ... -
Stress concentrations in bone cement : a critical distance approach
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2009)Bone cement is a biomaterial which is used in the fixation of orthopaedic implants. Despite its extensive use it is regarded as the 'weak link' in cemented arthroplasties, fatigue failure of the cement mantle being a major ... -
The cellular transducer in damage-stimulated bone remodelling
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)People with osteoporosis, osteopenia or weight baring joint replacement, due to an altered loading configuration, are more susceptible to microdamage accumulation than normal human beings as are athletes who undertake ... -
Mechanical properties of diamond impregnated cobalt metal matrix
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Diamond Impregnated Metal Matrix (DIMM) composite materials are a class of materials used in cutting and drilling of stone and construction materials. This thesis examined the effects of diamond size and diamond concentration ... -
Targeted bone remodelling : investigating the scissors model
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)Bone is continually being removed and replaced through the actions of basic multicellular units (BMU). This constant upkeep is necessary to remove microdamage and thus maintain the integrity of the bone. Microdamage forms ... -
The effects of a sliding air bubble on heat transfer from an inclined surface
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)An investigation into the effect of a single sliding air bubble on heat transfer from a submerged, inclined surface has been performed. It is known that bubbles, both vapour and gas, can increase heat transfer rates from ... -
Experimental investigations in turbomachinery noise-source identification
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)The exact contribution of each of the various core-noise sources within modern turboshaft engines to the noise radiated from the engine exhaust and into the surrounding environment is poorly understood. The objective of ... -
The fatigue behaviour of three-dimensional stress concentrations
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)The fatigue behaviour of complex three-dimensional notched components is a subject of great practical interest to industrial engineers. Unfortunately, the analysis of this type of feature presents problems for most assessment ... -
Time domain calculation of noise generated by a propeller in a flow
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 1997)In this thesis, the problem of calcultaing the noise from an acoustically subsonic aircraft propeller is approached using a "moving medium" method. An established theory of noise generation by rigid bodies in motion is ... -
EHD augmentation of convective boiling within a transparent heat exchange
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)This work investigated the influence of electrohydrodynamic forces on the two-phase flow patterns of HFE7000 refrigerant under convective boiling conditions. A flow loop was constructed which featured two novel transparent ... -
Cooling by high speed air jet in orthogonal machining operations
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)Changing environmental awareness has led manufacturing industry to give critical consideration to the use of conventional coolants and traditional cooling techniques in machining processes. Current research shows that ... -
Composition and mechanical properties of osteoarthritic subchondral trabecular tibial bone
(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. ... -
Bubble impingement and the mechanisms of heat transfer enhancement
(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 ... -
Computational simulation of the mechanobiological response of arterial tissue
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)Ischaemic heart disease, causing restriction of arterial blood flow to the heart tissue, can be treated with mechanical revascularisation treatments such as balloon angioplasty and stent implantation. One remaining limitation ... -
Three-dimensional vortex particle-in-cell technique
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004) -
Identification of a non-linear model for fluidelastic instability in a normal triangular tube array
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 1999) -
Interaction between fluidelastic instability and acoustic resonance
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2008) -
Resonant aeroacoustic source localisation in ducted bluff body flows
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011) -
Time-resolved noise source analysis in subsonic turbulent jets
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
