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 ... -
Engineering cartilage or endochondral bone: A comparison of different naturally derived hydrogels.
(2015)Cartilaginous tissues engineered using mesenchymal stem cells (MSCs) have been shown to generate bone in vivo by executing an endochondral programme. This may hinder the use of MSCs for articular cartilage regeneration, ... -
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 ... -
An experimental-numerical study of heat transfer enhancement in a minichannel using asymmetric pulsating flows
(2023)The development of current and next generation high performance electronic devices has led to miniaturization in more densely packed spaces. The increasing power levels has resulted in ever-increasing heat flux densities ... -
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 Transfer Behaviour and Flow Field Characterisation of Impinging Synthetic Jets for a Wide Range of Parameters
(ASME, 2010)Impinging synthetic jets are considered as a potential solution for convective cooling, in applications that match their main characteristics (high local heat transfer rates, zero net mass flux, scalability, active control). ... -
High dynamic range whole-field turbulence measurements in impinging synthetic jets for heat transfer applications
(2010)For applications requiring high local heat transfer rates, recent research has shown that impinging synthetic jets perform comparably to continuous jets, yet without needing external mass flow input. In spite of recent ... -
Liquid immersion thermal management of lithium-ion batteries for electric vehicles: An experimental study
(2023)The thermal and electrical performance of lithium-ion batteries subjected to liquid immersion cooling conditions in a dielectric fluid has been experimentally investigated in this study. A single 26650 LiFePO4 cylindrical ... -
Microstructure and Micro Hardness of Friction Stir Welded AA2024-T3 Joints
(2014)Macrostructure, microstructure and micro hardness of friction stir welded AA2024 - T3 joints was studied. The influence of tool pin profile on the microstructure and hardness of these joints was examined. Square, ... -
Numerical Evaluation of Fatigue Strength on Mechanical Notched Components under Multiaxial Loadings
(Elsevier, 2011)This paper deals with the fatigue behaviour of complex, three-dimensional, stress concentrations under multiaxial loadings. Starting from the stress field obtained by means of a linear elastic analysis and taking advantage ... -
Performance analysis of a prototype small scale electricity-producing biomass cooking stove
(2015)An electrical generator has been integrated with a locally produced, biomass-fed clay cooking stove in rural Malawi. The generator produces small amounts of electricity based on the thermoelectric effect. Five demonstrator ... -
Performance of a Closed Cycle Power Takeoff for a Shore-Based Wave Energy Device
(2023)A promising class of devices for ocean wave energy conversion is called the oscillating water column in which the wave power is transferred to an airflow that rotates a turbine. A closed cycle power takeoff (CCPTO), in ...
