3D Bioprinted Cartilaginous Templates as Developmentally Inspired Implants for Large Bone Defect Regeneration
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2022)Whilst bone possesses an inherent capacity for regeneration, defects above a critical size cannot heal on their own. Damaged or diseased bone can be treated using autografts or a range of different bone grafting biomaterials, ... -
A Bridgman Furnace Front Tracking Model
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2015)The Bridgman furnace is widely used in industry and research, mainly because it provides a means to directionally solidify materials in a controlled manner, so that the resulting microstructure, and hence material properties, ... -
An Argument for the Use of Multiple Segment Stents in Curved Arteries
(2011)Stenting of curved arteries is generally perceived to be more challenging than straight vessels. Conceptually implanting multiple shorter stents rather than a single longer stent into such a curved artery represents a ... -
Columnar and equiaxed solidification in a microgravity environment ? The CETSOL project
(2017)The formation of the microstructure and the grain structure during solidification is affected by buoyancy-driven flow and movement of crystals growing in the melt. To allow for pure diffusive solidification conditions, ... -
Columnar to Equiaxed Transition in Peritectic TiAl Based Alloy Studied by a Power-Down Technique
(Trans Tech Publications Inc., 2014) -
Conditions for CET in a gamma TiAl alloy
(2015)The solidification of gamma TiAl alloys is of interest to the aerospace and automotive industries. A gamma TiAl multicomponent alloy: Ti–45.5Al–4.7Nb–0.2C–0.2B (at. %) has been the focus of a study to investigate the ... -
Dynamic compression can inhibit chondrogenesis of mesenchymal stem cells.
(2008)The objective of this study was to investigate the influence of dynamic compressive loading on chondrogenesis of mesenchymal stem cells (MSCs) in the presence of TGF-?3. Isolated porcine MSCs were suspended in 2% agarose ... -
An experimental-numerical method for estimating heat transfer in a Bridgman furnace
(2014)Direct measurement of heat flux and heat transfer coefficients in a Bridgman furnace is not always possible using traditional methods. This study characterised a vertical tubular Bridgman furnace using experimental data ... -
A Front Tracking Model for Transient Solidification of Al-7wt%Si in a Bridgman Furnace
(2012)The Bridgman furnace is widely used in industry and research. This paper outlines a working onedimensional model for tracking the columnar solidification front in a Bridgman furnace where the pulling velocity, and hence ... -
Heat pipe-based radiator for low grade geothermal energy conversion in domestic space heating
(2011)A severe technical drawback of geothermal heat pumps (GHPs) is the fact that the nominal operating temperature available for domestic space heating is typically in the region of 50?C. This is 25?C to 40?C less than ... -
The influence of ventilation tube design on the magnitude of stress imposed at the implant/tympanic membrane interface
(Elsevier, 2008)The design of ventilation tubes or grommets is thought to have a considerable influence on their performance. A computational model (finite element method) was used to investigate the significance of four design parameters ... -
Jet heat transfer in the vicinity of a rotating grinding wheel
(Professional Engineering Publishing, 2006)Impinging jets are known as a method of achieving high convective heat transfer coefficients. One potential application of impinging jet heat transfer is the air jet cooling of a grinding process. A grinding process ... -
Macroscale modelling of Bridgman furnace solidification for the prediction of texture evolution and columnar to equiaxed transition
(Institute of Physics, 2016)Bridgman furnaces are commonly used in solidification research owing to their convenience when setting the desired solidification parameters, specifically, the nominal temperature gradient and nominal growth rate. The work ... -
A pressure-based estimate of synthetic jet velocity
(2007)Synthetic jets are used for active flow control and enhanced heat transfer, and are typically generated by an orifice connected to a cavity with movable diaphragm actuator. Low-power operation is achieved by matching ...
