    • Computational study of heat transfer in subsea deadlegs for evaluation of possible hydrate formation 

      Andersen, Hilde (Master thesis, 2007)
      The background for this project is the request of achieving more knowledge of the temperature and velocity fields in different subsea deadleg geometries. This is important to avoid hydrate formation in subsea equipment. ...

    • Gas explosions in process pipes 

      Kristoffersen, Kjetil (Doctoral theses at NTNU;2004:79, Doctoral thesis; Peer reviewed, 2004)
      In this thesis, gas explosions inside pipes are considered. Laboratory experiments and numerical simulations are the basis of the thesis. The target of the work was to study gas explosions in pipes and to develop numer- ...

    • Hydrogen gas explosions in pipelines, modeling and experimental investigations 

      Knudsen, Vegeir (Doctoral thesis; Peer reviewed, 2006)
      Gas explosions in closed pipes with a single obstacle have been investigated both numerically and experimentally. Most of the work is related to hydrogen and air mixtures, but other fuels have also been used. At the present ...

    • Modeling and simulation of post combustion CO2 capturing 

      Greer, Timothy (Master thesis, 2008)
      A dynamic model for the chemical absorption of carbon dioxide in Monoethanolamine is developed and implemented. The model includes absorption tower, de-absorption tower, reboiler, condenser and rich/lean heat exchanger. ...

    • Nosé-Hoover simulations of aqueous mixtures of small alcohols 

      Holta, Randi Toreskås (Doctoral thesis; Peer reviewed, 1996)
      We have performed constant energy and constant temperature equilibrium molecular dynamics simulations of model liquids of water, methanol, and ethanol, and of the binary aqueous mixtures of the alcohols at mole fractions ...

    • Statistical estimation of loads from gas explosions 

      Høiset, Stian (Doctoral theses at NTNU;1998:23, Doctoral thesis; Peer reviewed, 1998)
      In the design of structures in the offshore and process industries, the possibility of a gas explosion must always be considered. This is usually incorporated by performing explosion simulations. However, estimations based ...

    • Transient response to shock loads in biogas processes 

      Helgestad, Haiyun Zhang (Master thesis, 2006)
      Active culture which is in a semi steady state was extracted from an anaerobic digestion reactor, transferred to a continuously stirred batch reactor with rather small head space. 35±1ºC was controlled for the reactor to ...
