    • Multiphysics Simulation of Infrared Signature of an Ice Cube 

      Khawaja, Hassan Abbas; Rashid, Taimur; Eiksund, Oddmar; Broadal, Eivind; Edvardsen, Kåre (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 ...

    • Multiphysics Simulation of Infrared Signature of an Ice Cube 

      Khawaja, Hassan Abbas; Rashid, Taimur; Eiksund, Oddmar; Brodal, Eivind; Edvardsen, Kåre (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 ...

    • Review of marine icing and anti-/de-icing systems 

      Rashid, Taimur; Khawaja, Hassan Abbas; Edvardsen, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-17)
      The aim of this work is to review the phenomenon of icing in marine operations. The focus is on two main sources of icing, namely atmospheric and sea spray. The literature reveals that sea spray icing is the main contributor to marine icing. This work discusses the available ice accretion prediction models on ships and offshore structures. It also reviews the anti-/de-icing technologies that can be ...

    • Roll to Roll coating of carbon nanotube films for electro thermal heating 

      Rashid, Taimur; Liang, Hsin-Ling; Taimur, Madiha; Chiodarelli, Nicolò; Khawaja, Hassan; Edvardsen, Kåre; De Volder, Michael (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-27)
      Carbon nanotube (CNT) films are gaining traction in applications such as transparent conductive films, electro-magnetic shields and thin film heaters. However, to date, few cost-effective large-area CNT coating methods have been reported. Here, we present a roll-to-roll (R2R) slot-die coating process for thin film CNT heaters. In this process, a CNT suspension is continuously coated on a PET film ...

    • Sea-spray measurement tools and technique employed in marine icing field expeditions: A critical literature review and assessment using CFD simulations 

      Dhar, Sushmit; Naseri, Masoud; Khawaja, Hassan Abbas; Samuelsen, Eirik Mikal; Edvardsen, Kåre; Barabady, Javad (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-24)
      Sea-spray icing resulting from sea spray droplets accreting on exposed surfaces poses a significant safety concern for vessels and marine structures operating in cold climate regions. One of the key parameters determining the amount of ice accretion is the quantity of incoming sea spray, which eventually comes in contact with the structure in the presence of brine film freezing temperature. Hence, ...

    • Spray Icing on ONEGA Vessel- A Comparison of Liquid Water Content Expressions 

      Dhar, Sushmit; Samuelsen, Eirik Mikal; Naseri, Masoud; Aarsæther, Karl Gunnar; Edvardsen, Kåre (Journal article; Tidsskriftartikkel, 2022)
      The hazards associated with ice accretion primarily due to impinging freezing sea spray on ship structures are considered among serious safety concerns for ships operating in the colder regions. An accurate sea-spray icing-estimation model to evaluate the ice accumulation during operations in these regions can make marine operations safer. The accuracy of the present icing models for estimating icing ...
