    • 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 ...

    • CO2 Absorption Efficiency and Heat Consumption Measured at High Gas to Liquid Ratios in Laboratory Rig 

      Øi, Lars Erik; Hansen, Per Morten; Henriksen, Mathias (Journal article; Peer reviewed, 2017)
      A laboratory rig for CO2 absorption into amine solvents including desorption has been in operation at University College of Southeast Norway for several years. Measurements of CO2 removal efficiency and heat consumption ...

    • Explosion characteristics for Li-ion battery electrolytes at elevated temperatures 

      Henriksen, Mathias; Vågsæther, Knut; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, Dag (Peer reviewed; Journal article, 2019)
      Li-ion batteries are used in electronic devices and electric cars, yet they create safety concerns due to the possibility of the release of combustible materials. The electrolyte, one of the main components in a Li-ion ...

    • Laminar burning velocity in hydrogen-oxygen-nitrogen mixtures 

      Thang, Yone Kyin (Master thesis, 2022)
      As today’s world is demanding a greener environment where greenhouse gas emission and global warming are much reduced, hydrogen has become the most promising element among others from periodic table. As today’s world is ...

    • Laminar burning velocity of gases vented from failed Li-ion batteries 

      Henriksen, Mathias; Vaagsaether, K.; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, D. (Journal article; Peer reviewed, 2021)
      In the last decade, several fires and explosions caused by Li-ion batteries (LIBs) have been reported. This can be attributed to the thermal runaway and catastrophic failures of LIBs that release combustible gases, which ...

    • Laminar burning velocity of the dimethyl carbonate–air mixture formed by the Li-ion electrolyte solvent 

      Henriksen, Mathias; Vågsæther, Knut; Gaathaug, Andre Vagner; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, Dag (Peer reviewed; Journal article, 2020)
      If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this ...

    • 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 ...

    • Numerical study of premixed gas explosion in a 1-m channel partly filled with 18650 cell-like cylinders with experiments 

      Henriksen, Mathias; Vågsæther, Knut; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, Dag (Peer reviewed; Journal article, 2022)
      Abused and defective Li-ion cells can cause a catastrophic failure of a Li-ion battery (LIB), leading to severe fires and explosions. In recent years, several numerical and experimental studies have been conducted on the ...

    • Simulation of burning velocities in gases vented from thermal run-a-way lithium ion batteries 

      Johnsplass, Jonathan; Henriksen, Mathias; Vågsæther, Knut; Lundberg, Joachim; Bjerketvedt, Dag (Journal article; Peer reviewed, 2017)
      This paper describes the results from simulations of laminar burning velocities in the premixed air and flammable gases vented from abused Li-ion batteries. The released mixture from such batteries contain mixtures of ...

    • A study of premixed combustion of gas vented from failed Li-ion batteries 

      Henriksen, Mathias (Doctoral dissertations at the University of South-Eastern Norway;109, Doctoral thesis, 2021-11-25)
      As the world moves towards more clean and suitable energy sources such as wind and solar, there is an increasing demand for energy storage systems. Lithium-ion batteries (LIBs) are today the leading electrical energy storage ...

    • 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 ...
