• 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 ...
    • Experimental Study of Deflagration to Detonation Transition in Hydrogen-Air Mixtures 

      Gaathaug, André Vagner (Doctoral dissertations at TUC;2015:1, Doctoral thesis; Peer reviewed, 2015-04-29)
      Gas explosions in a square channel have been investigated with a main focus on the deflagration to detonation transition (DDT). The gas mixtures were hydrogen and air at different concentrations. This work have been motivated ...
    • 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 ...
    • Flame propagation in a transparent pipe with a single obstruction 

      Gaathaug, André Vagner (Master thesis, 2008)
      This report treats the problem of hydrogen explosions. The background for this thesis was based upon earlier work done by Bjerketvedt D., Vågsæther K. and Knudsen V. They investigated hydrogen explosions in a steel pipe ...
    • 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 ...
