    • Comparison of results from some chemical dispersion models and hazard prediction and assessment tools 

      Tørnes, John Aasulf; Endregard, Monica; Vik, Thomas; Bjerke, Audun (2010)
      Dispersion models and hazard prediction and assessment software tools are used to assess consequences from dispersion of hazardous materials, such as toxic chemicals. Such tools can be employed during and after an event ...

    • Consequence assessment of indoor dispersion of sarin-A hypothetical scenario 

      Endregard, Monica; Reif, Bjørn Anders Pettersson; Vik, Thomas; Busmundrud, Odd (2010)
      The objective of this study is to provide a hypothetical scenario of indoor dispersion of the highly toxic nerve agent sarin in a large building, which can be used as a starting point for discussion, planning, training and ...

    • Dispersion simulation for CBRNE accident coordination training 

      Vik, Thomas; Gjesdal, Thor; Helgeland, Anders (Forsvarets forskningsinstitutt, 2024-10-09)
      FFI has developed a virtual training system that can be used to train incident leaders and responders in the mitigation of accidents involving hazardous substances. The virtual training system was successfully used during ...

    • Implementation of a new and improved evaporation model in Fluent 

      Vik, Thomas; Reif, Bjørn Anders Pettersson (2011-01-13)
      The release and dispersion of toxic chemicals can cause a threat to military personnel and the population at large. In order to develop and implement appropriate protective capabilities and plan mitigating measures, ...

    • Indoor dispersion of sarin by evaporation from liquid pools 

      Aalbergsjø, Siv Gundrosen; Vik, Thomas (2016-08-15)
      The threat of terrorist actions involving toxic chemicals is present in today’s society, and there is therefore a need for appropriate emergency response planning. An accurate description of the release and dispersion ...

    • Leakage rate of the nerve agent tabun from sea-dumped munition 

      Tørnes, John Aasulf; Vik, Thomas; Kjellstrøm, Tomas Tungen (2020-10)
      The leakage rate of nerve agents from corroded munition on the sea floor has been estimated by using table sugar as a simulant for the nerve agent tabun. Laboratory experiments were conducted with a full-size model of a ...

    • Modeling the evaporation from a thin liquid surface beneath a turbulent boundary layer 

      Vik, Thomas; Reif, Bjørn Anders Pettersson (2010)
      The release and dispersion of toxic chemicals can cause a threat to military personnel and the population at large. In order to develop and implement appropriate protective capabilities and plan mitigating measures, ...

    • MODITIC - report on source term modelling 

      Burkhart, Stephane; Björnham, Oscar; Vik, Thomas; Leroy, Guillaume (2016-10-13)
      The European Defence Agency (EDA) project B-1097-ESM4-GP “MOdelling the DIspersion of Toxic Industrial Chemicals in urban environments” (MODITIC) has in the period from 2012 to 2016 studied the release and transport of ...

    • Preliminary assessment of the vertical release of liquefied chlorine inside a depression 

      Vik, Thomas; Reif, Bjørn Anders Pettersson (2009)
      Toxic industrial chemicals (TICs) are used in most places and can pose a threat due to accidents, terror, or sabotage. Many of the most common TICs are gasses at ambient atmosphere, such as chlorine, ammonia, and sulfur ...

    • Preliminary numerical simulation of the dispersion of chlorine vapour in a mock urban environment for the Jack Rabbit II field trials 

      Vik, Thomas; Wingstedt, Emma M. M.; Reif, Bjørn Anders Pettersson (2016-02-02)
      The release and dispersion of toxic industrial chemicals as a result of accidents, terrorism, or sabotage represent a possible hazard for life and health. Such chemicals are often transported and stored as condensed ...

    • Simple source description for dense gas releases 

      Vik, Thomas; Fossum, Hannibal; Helgeland, Anders (2024-01-02)
