Surface heat transfer due to sliding bubble motion
(2009)
The presence of a rising bubble in a fluid can greatly enhance heat transfer from adjacent heated surfaces
such as in shell and tube heat exchangers and chemical reactors. One specific case of this is when a bubble
impacts ...
Time averaged and fluctuating heat transfer measurements in an atomising mist jet nozzle
(ASME, 2009)
Much is already known about the heat transfer characteristics of impinging air jets, and they are widely used in many engineering applications. There currently exist many correlations describing such characteristics. ...
Heat transfer and air temperature measurements of an impinging synthetic air jet
(2009)
Synthetic jets are a relatively new technology that can achieve high rates of heat transfer. They have been
shown to out-perform comparable steady impinging jets without the need for an external air supply system.
The ...
The control of environmental tobacco smoke: a policy review
(2009)
According to World Health Organisation figures, 30% of all cancer deaths, 20% of all coronary heart diseases and strokes and 80% of all chronic obstructive pulmonary disease are caused by cigarette smoking. Environmental ...
Pedestrian Risk from Cars and Sport Utility Vehicles - A Comparative Analytical Study
(2006)
Analysis of real-world crash data from the USA shows that 11.5 per cent of
pedestrians struck by large sport utility vehicles (SUVs) are killed, compared with 4.5 per cent
of pedestrians struck by passenger cars. The ...
Audio noise mapping for virtual urban simulations: enhancing public awareness
(2007)
One of the key difficulties with urban environmental noise mapping is disseminating results
from noise studies in a manner that is easily under
stood by the general public. Indeed, it is
one of the requirements of the ...
Noise Source Location in Turbomachinery Using Coherence Based Modal Decomposition (AIAA 2009-3367)
(2009)
Coherence based source analysis techniques can be used to identify the contribution of
turbomachinery core noise sources to pressure measurements in the far-field. The usual
approach is to locate a measurement sensor ...
Passenger Requirements of a Public Transport Ticketing System
(2005)
Currently in Dublin the system of public transport ticketing is under review and there are plans to introduce a multi-modal, multi-operator ticketing system. It is planned that this system would be operated via smart card ...
