Review of Peltier and Resistive Heating Elements through Infrared Imaging
(Conference object; Konferansebidrag, 2016-12-08)
The study includes the review of the heating elements to develop the fundamental understanding. The heating elements to be investigated are Peltier and Resistive types. Both have different working principles and they are used in various industrial applications for cooling and heating purposes. The Infrared (IR) wavelength is emitted by each object at a temperature above absolute zero. IR light is ...
Ice Detection Setup Using Infrared and Active Heating
(Conference object; Konferansebidrag, 2015)
Considering the cold environment operations, ice accretion can occur at a rapid pace and can adversely affect the operations. In such scenario, ice detection is
useful for the ice mitigation and removal upon the marine and offshore structures. Various techniques exist in the literature to detect the icing mainly utilizing its
physical or electromagnetic properties. The parameters measured by these ...
Active Infrared Observation for Ice Detection in Anti/De-Icing Systems for Marine Applications in Arctic Region
(Conference object; Konferansebidrag, 2016-12-08)
The number of shipping operations is on the rise in the Arctic region. As a result of these increased activities, significant challenges are being encountered with respect to safety and reliability. One of the challenges is an accretion of ice. The icing on ships and offshore structures is caused by atmospheric sources and sea spray. The sea spray is the main source of icing and is generated by the ...
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 Ice Block
(Conference object; Konferansebidrag, 2015-08-23)
Marine operations in cold climates are subjected to
heavy ice accretion, which can lead to heavy ice loads causing
safety concerns. Atmospheric and sea spray icing can cause
severe ice accretion on structures. Ice detection over the
relatively larger surface area of marine platforms and vessels
could be significant for ice mitigation and its removal in cold
climates. A thermal ice signature ...
Multiphysics Simulation of Infrared Signature of an Ice Cube
(Peer reviewed; Conference object; Konferansebidrag, 2015-12-11)
This poster presents the Multiphysics numerical methodologies used to simulate the Infrared (IR) signature of an ice cube when taken out of the cold environment
(-28 C) and allowed to warm at room temperature conditions by means of natural convection. The ice cube is chosen to simplify the geometry. The cubical
geometry can be discretized simply and hence allows easy application of Multiphysics ...
