    • CFD-Simulations of inhomogeneous H2-air explosions 

      Aghaabbasi, Omid (Master thesis, 2021)
      Since demands for energy resources increase globally in recent years due to growth of application consumption, finding alternative resources for traditional fossil fuels raises. These current fuels are diminishing continuously ...

    • Hydrodynamics - calculation of added mass on complex objects 

      Kaasa, Sondre (Master thesis, 2021)
      Added mass er et komplekst fenomen innen hydrodynamikk, hvor det finnes lite forståelse i industrien. Dermed var motivasjonen for dette arbeidet å bygge kunnskap innen hydrodynamikk og numerisk modellering av hydrodynamiske ...

    • Investigation of the performance of a pilotscale CO2 desorption column using CFD simulations 

      Shakeri, Avishan (Master thesis, 2021)
      Technology Center Mongstad (TCM) is the world’s largest and most flexible test facility for amine based CO2 absorption and desorption. This master thesis is based on an operational problem at TCM where excess liquid loading ...

    • Minimum ignition energy of hydrogen and hydrogen-carrying fuels 

      Jakar, Sarthak (Master thesis, 2022)
      Hydrogen is touted to be the fuel of the future leading to low carbon emissions globally. But as this fuel is being popularized all over the world for all the industry sectors, very little is known about the combustion ...

    • Modeling and simulation of hydrogen flow in a maritime fuel cell system 

      Valand, Stian (Master thesis, 2022)
      The climate change challenge is one of today's greatest challenges, and the need to reduce emissions is more significant than ever. Hydrogen can be a potential zero-carbon fuel, and together with a maritime fuel cell system, ...

    • Modeling of evaporation of hydrogen during accidental releases 

      Afzali, Mojtaba (Master thesis, 2021)
      Hopefully, in the near future, liquid hydrogen will be commonly utilized as energy. The cleanest fuel that the primary limit of producing and using it, is safety issues. High possibility safety issues are generated by large ...

    • Safety review and risk study for hydrogen storage 

      Vindenes, Cathrine (Master thesis, 2022)
      The energy sector is rapidly adjusting towards the green change by cutting emissions and using more renewable energy sources. The interest in hydrogen economy has increased in the last decade due to environmental concerns ...

    • Simulation of hydrogen tank refueling 

      Salcido Sanchez, Jose Luis (Master thesis, 2021)
      Several simulations of hydrogen filling process for a type IV tank were completed using openFOAM Computational Fluid Dynamics (CFD) open-source code. CFD codes have been proven to be a useful method for estimating temperature ...

    • Simulation of Hydrogen Tank Refuelling 

      Mojarrad, Masih (Master thesis, 2020)
      As an alternative to fossil fuels and as a sustainable energy carrier, there are considerable interestsin investigating hydrogen. Hence, it seems significant to evaluate the behavior of hydrogen in refueling or storing. ...

    • Teoretisk analyse av rørstrømning under flytende hydrogenbunkring 

      Aavik, Nils Jørgen (Master thesis, 2022)
      Denne oppgaven hadde som mål å bruke teoretiske modeller for å estimere trykktapet ved flytende hydrogenbunkring og å studere hydrogenfasen gjennom systemet. Massestrøm studeres også ved å bruke to metoder for kurvetilpasning ...
