    • Development of LES inflow conditions for turbulent boundary layers 

      Wingstedt, Emma M. M.; Vartdal, Magnus; Osnes, Andreas N.; Tutkun, Murat (2013-10-31)
      Computational Fluid Dynamics (CFD) is currently the only known physically based method to model dispersion and transport of aerosols and gases in complex urban environments. One of the main challenges with CFD simulations ...
    • A modelling study of the flow pattern in a rotating drum for aerosol aging 

      Reif, Bjørn Anders Pettersson; Wingstedt, Emma M. M.; Pedersen, Kristin (2009)
      Aerosols are small droplets or particles suspended in a gas and they can contain microorganisms or other harmful substances. It is therefore of great importance to gain more knowledge about them, for example their survival ...
    • MODITIC - large-eddy simulations of dense gas dispersion in urban environments 

      Eriksson, Daniel; Osnes, Andreas N.; Parmhed, Oskar; Wingstedt, Emma M. M.; 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) (2012 – 2016) has studied the release and transport of neutral and non-neutral ...
    • MODITIC - Reynolds-averaged Navier-Stokes simulations of dense gas dispersion in urban environments 

      Burkhart, Stephane; Burman, Jan; Eriksson, Daniel; Wingstedt, Emma M. M. (2016-10-13)
      The European Defence Agency (EDA) project B-1097-ESM4-GP “MOdelling the DIspersion of Toxic Industrial Chemicals in urban environments” (MODITIC) (2012 – 2016) has studied the release and transport of neutral and non-neutral ...
    • MODITIC : modelling the dispersion of toxic industrial chemicals in urban environments 

      Endregard, Monica; Burkhart, Stephane; Burman, Jan; Gentilhomme, Olivier; Robins, Alan; Wingstedt, Emma M. M.; Reif, Bjørn Anders Pettersson; Persson, Leif; Brännström, Niklas; Parmhed, Oskar (2016-10-13)
      The main objective of the MODITIC (Modelling the disperison of toxic industrial chemicals in urban environments) project is to enhance our fundamental understanding of the physical processes and the associated challenges ...
    • MODITIC wind tunnel experiments 

      Robins, Alan; Hayden, Paul; Wingstedt, Emma M. M. (2016-10-13)
      The European Defence Agency (EDA) project B-1097-ESM4-GP “MOdelling the DIspersion of Toxic Industrial Chemicals in urban environments” (MODITIC) (2012 – 2016) has studied the release and transport of neutral and non-neutral ...
    • Numerical simulations of particle dispersion in an urban area 

      Wingstedt, Emma M. M.; Reif, Bjørn Anders Pettersson (2012-06-27)
      In this study the transport and deposition of particles released from different source locations, and with different wind conditions, in a realistic urban area have been investigated. Two different scenarios have been ...
    • 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 ...
    • Simulation of bomb residue deposition following the Oslo bombing July 22, 2011 

      Wingstedt, Emma M. M.; Fossum, Hannibal E.; Reif, Bjørn Anders Pettersson (2012-11-16)
      The objective of the present study is to simulate the dispersion and make an assessment on the shape and concentration of the deposition of particle residues originating from the improvised explosive device used on July ...
    • Transport and dispersion of non-neutral toxic industrial chemicals in an urban environment 

      Wingstedt, Emma M. M.; Vik, Thomas; Reif, Bjørn Anders Pettersson (2012-08-31)
      The main focus in this study was to investigate the difference between the dispersion and transport process of non-neutral and passive gas release, respectively, in an urban area. The method used was the LES approach, ...
