    • An experimental study of temperatures in cloud from release of flashing liquid CO2 in 3m long channel. 

      Adhikari, Amrit; Gaathaug, André Vagner; Bjerketvedt, Dag; Vågsæther, Knut (Journal article; Peer reviewed, 2014)
      Flashing of the liquid CO2 is an accidental hazards that may occurs in many industrial sector such as, process industries, carbon capture and storage projects, crude oil extraction process etc. Sometimes the accidental ...

    • Boiling liquid expanding vapour explosion in CO2 small scale experiments 

      Bjerketvedt, Dag; Egeberg, Kjersti; Ke, Wei; Gaathaug, André Vagner; Vågsæther, Knut; Nilsen, Sandra Hennie (Journal article; Peer reviewed, 2011-04)
      Carbon capture and storage systems require handling large volumes of high pressure CO2. Having thorough knowledge of the related hazards is essential, as is knowing how to prevent, detect, control and mitigate accidents. ...

    • Detonation propagation in stratified reactant layers 

      Gaathaug, André Vagner; Bjerketvedt, Dag; Lundberg, Joachim; Vågsæther, Knut (Journal article; Peer reviewed, 2017)
      A numerical investigation of detonation propagation in stratified reactant layers is presented in this paper. It is baesed on the reactive Euler equations using a two step chemical kinetics approach. The numerical simulations ...

    • Doctorateness across Higher Education Institutions in Norway 

      Burner, Tony; Bjerkholt, Eva; Gaathaug, André Vagner; Kleiven, Synne; Ljoså, Tone Marte (Journal article; Peer reviewed, 2020)
      This article investigates doctorateness in Norway by evaluating the juridical regulations for doctoral studies at all PhD-awarding universities and university colleges according to the following categories: admission, ...

    • Experimental Study of Gas Explosions in Hydrogen Sulfide-Natural Gas-Air Mixtures 

      Gaathaug, André Vagner; Bjerketvedt, Dag; Vågsæther, Knut; Nilsen, Sandra Hennie (Journal article; Peer reviewed, 2014-08-21)
      An experimental study of turbulent combustion of hydrogen sulfide (H2S) and natural gas was performed to provide reference data for verification of CFD codes and direct comparison. Hydrogen sulfide is present in most crude ...

    • Experiments with flame propagation in a channel with one obstacle and premixed H2-air 

      Gaathaug, André Vagner; Bjerketvedt, Dag; Vågsæther, Knut (Conference object; Peer reviewed, 2009-07)
      This abstract presents experimental results of flame propagation in a square channel with a single obstacle. The background for the experimental study was to investigate how a flame propagated when and after the flame ...

    • Open Active Contour Model For Front Tracking Of Detonation Waves 

      Maharjan, Samee; Lysaker, Ola Marius; Gaathaug, André Vagner (Journal article; Peer reviewed, 2017)
      This paper presents an image processing framework for tracking the front of the detonation wave from a sequence of images. The images are captured by high speed camera during a laboratory gas explosion experiment. By ...

    • Using Image Processing for Flame Diagnostics 

      Lundberg, Joachim; Henriksen, Mathias; Gaathaug, André Vagner (Journal article; Peer reviewed, 2017)
      An image processing routine was developed to determine the flame height of a hydrogen jet flame. Two different techniques was tested, where one where based on Wiens distribution of a black body and one based on intensity ...
