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 Design Study of an Atmospheric Icing Sensor
(Peer reviewed, 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, 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 ...
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 ...
A field study of atmospheric icing analysis in a complex terrain of the high north
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-12)
Analyses of atmospheric icing events hold the key for computing the significant parameters leading to icing load calculations. In the cold regions of the high north, atmospheric icing loads on structures become important when it comes to design and safety of infrastructures. Furthermore, icing load calculations over a certain period of time provide a vital input for designers to improve the ...
Atmospheric ice monitoring system operation at Remote locations in cold region
(Journal article; Peer reviewed; Tidsskriftartikkel, 2013)
The problems encountered in installation, maintenance and operations of equipment in the cold climate regions are far more complicated than others. The contributing factors and problems that can affect the system operation and performance should be identified, assessed and focused within well-defined parameters before its installation in cold climate regions. The harsh cold environment, could not ...
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 ...
Atmospheric Icing Sensors - Capacitive Techniques
(Peer reviewed, 2013-01-22)
The application of capacitive sensing technique is widely distributed in different physical domains primarily because of the diversity in dielectric permittivity and due to its minimum loading error and inertial effects. Atmospheric ice is a complex mixture of water, ice and air which is reflected in its complex dielectric constant. There are many existing atmospheric icing sensors but only few are ...
