State of the Art Review of Atmospheric Icing Sensors
(Journal article; Peer reviewed; Tidsskriftartikkel, 2016-03-31)
A state of the art review of atmospheric icing sensors is presented in this article, in order to
understand their design and working principle for future developments. It is found that most atmospheric icing
sensors which are capable of delivering maximum information are based upon direct measurement of the
physical properties (electrical or mechanical) of atmospheric ice. Some field measurements ...
Numerical study of atmospheric ice accretion on rotating geometric cross sections with fins
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-12)
This paper describes the numerical study of atmospheric ice accretion on rotating geometric cross sections,
circular,
hexagon and square
, all having fins, to select an optimum geometric cross section for use as a rotating part of a newly-
proposed designed icing sensor. Computational fluid dynamics-based numerical analyses were carried out in this research
work to understand and analyse the ...
Multiphysics based Numerical Study of Atmospheric Ice Accretion on a Full Scale Horizontal Axis Wind Turbine Blade
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08)
Atmospheric icing on wind turbines have been recognized as a hindrance
to the development of the wind power in cold regions, where uncertainty
surrounding the effects of icing on energy production may prevent
otherwise good wind resources from being utilized. This research paper is
focused on to numerically simulate the rate and shape of atmospheric ice
accretion on a full-scale horizontal axis ...
Multiphysics Based Design Study of an Atmospheric Icing Sensor
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016)
A design study of an atmospheric icing sensor is presented in this article. The proposed design of the sensor is aimed to detect an atmospheric icing event, to determine ice type as well as to measure icing load, icing rate and melting rate. This sensor is constantly slowly rotating cylinder with four fins which measure atmospheric icing load and icing rate using rotational load measurement technique. ...
Experimental validation of icing rate using rotational load
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-04-16)
Icing load and icing rate are necessary feedback variables for an intelligent anti/de-icing systemtowork effectively
in harsh cold environment of high north. These parametersmay be measured by axial loadings or by rotational
loadings, as a function of current demand. However the former may not necessarily be dynamic, whereas the
later necessarily be rotational. Sufficiently at a fixed rpm, a ...
