    • 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 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 ...

    • 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 ...

    • 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 ...
