Study of Wind Chill Factor using Infrared Imaging
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
This paper presents a study of wind chill factor using infrared imaging. Wind chill factor is the cooling sensation due to the exposure of wind temperature environment. The wind chill factor depends on air temperature, wind velocity, and humidity. Wind chill poses serious health risks. Various wind chill index models are given in the literature. The wind chill factor is closely associated with the ...
Determination of Thermal Properties of Fresh Water and Sea Water Ice using Multiphysics Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
This paper presents a methodology to determine the thermal conductivity of ice using multiphysics analysis. This methodology used a combination of both experimentation and numerical simulation. In the experimental work, an ice block is observed using an infrared camera. The results reveal the variation in temperature over the surface. These results are dependent on two primary heat transfer parameters, ...
Multiphysics Simulation of Infrared Signature of an Ice Cube
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
This paper presents numerical methodologies to simulate the Infrared (IR) signature of an ice cube. The ice was frozen in a cold environment (-28<sup>o</sup>C) and allowed to have uniform temperature throughout. It was then taken out and let to warm at room temperature conditions by means of natural convection. A 3D transient heat equation is solved using three different methodologies. In the first ...
Ice Detection of Pure and Saline Ice Using Infrared Signature
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-30)
The paper shows the possible implementation of an Infrared (IR) ice detection technique. In respect of safety in marine operations, saline ice detection can be significant for automated de-icing systems. Experimentation is performed to observe and detect saline and pure ice samples. The discussed detection mechanism is unique and differs from passive IR detection by introducing the self-heating ...
Infrared Thermal Signature Evaluation of a Pure and Saline Ice for Marine Operations in Cold Climate
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2015)
Marine operations in cold climates are subjected to abundant ice accretion, which can lead to heavy ice loads over larger surface area. For safe and adequate operations on marine vessels over a larger area, remote ice detection and ice mitigation system can be useful. To study this remote ice detection option, lab experimentation was performed to detect the thermal gradient of ice with the infrared ...
