Heat transfer mechanisms in an impinging synthetic jet for a small jet-to-surface spacing
(2009)Impinging synthetic jets have been identified as a promising technique for cooling miniature surfaces like electronic packages. This study investigates the relation between the convective heat transfer characteristics and ... -
Physically short crack propagation in metals during high cycle fatigue
(Elsevier, 2009)In metals, during high cycle fatigue on plain specimens, almost the entire fatigue life is spent as short crack initiation and propagation. The fatigue short crack life can be schematically divided into two subsequent ... -
Noise source identification for ducted fan systems
(American Institute of Aeronautics and Astronautics, 2008)Coherence based source analysis techniques can be used to identify the contribution of combustion noise in the exhaust of a jet engine and hence enable the design of noise reduction devices. However, when the combustion noise ... -
Non-linear Identification Applied to Broadband Turbomachinery Noise
(2008)Coherence based source analysis techniques can be used to identify the contribution of broadband noise sources in the exhaust of a gas turbine and hence enable the design of noise reduction devices. However, when the ... -
Noise Source Identification For Ducted Fan Systems (AIAA 2007-3693)
(2007)Understanding combustion noise source mechanisms, designing efficient acoustic liners and optimising active control algorithms for noise reduction requires the identification of the frequency and modal content of the ... -
Fluctuating fluid flow and heat transfer of an obliquely impinging air jet
(2008)Heat transfer to an obliquely impinging air jet is investigated experimentally. Distributions of the mean and the fluctuating component of the surface heat transfer are reported for a jet Reynolds number of 10,000, nozzle ... -
Part 1: scaffolds and surfaces.
(Elsevier, 2008)Every day thousands of clinical procedures are performed to replace or repair tissues in the human body that have been damaged through disease or trauma. Current therapies are focused on the replacement of the damaged ... -
Bubble enhanced heat transfer from a vertical heated surface
(Taylor & Francis, 2008)A rising bubble in a liquid can greatly enhance heat transfer from heated surfaces by acting like a bluff body, displacing fluid as it moves and via the wake generated by the bubble, increasing the mixing of the liquid. ... -
Natural convection around a horizontal heated cylinder: The effects of vertical confinement
(2003)Natural convection heat transfer from a single horizontal cylinder and a pair of vertically aligned horizontal cylinders is investigated. Surface heat transfer distributions around the circumference of the cylinders are ... -
Air jet cooling of brake discs
(Institution of Mechanical Engineers, 2008)This paper reports on an investigation of a novel approach to the cooling of brake discs, based on the application of impinging air jets. This has the capacity to enhance the heat transfer coefficients at the disc surface ... -
Modelling damage growth and failure in elastic materials with random defect distributions
(Royal Irish Academy, 2004)Failure in materials under cyclic loading occurs by the growth and propagation of cracks. If they are sufficiently numerous, the cracks can be considered to be continuously distributed in the material. In this paper, a ... -
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 ... -
Mechanobiology of embryonic limb development
(2007)Considerable evidence exists to support the hypothesis that mechanical forces have an essential role in healthy embryonic skeletal development. Clinical observations and experimental data indicate the importance of muscle ... -
Wear of grinding wheels - software for their selection
(2004)An existing model of the grinding process has been upgraded to predict grinding wheel wear as G ratios. It has been successfully benchmarked against experimental results for several combinations of coolant wheel and ... -
Control of Grinding Temperature by High Speed Air Jets
(Bled, 2004)Grinding, like other abrasive processes, may generate high local temperatures along the arc of cut. These can cause various forms of surface damage in the most sensitive finishing phase of the manufacturing cycle. Traditional ...
