• Early detection of smoldering in silos: Organic material emissions as precursors 

      Bluvshtein, Nir; Villacorta, Edmundo; Li, Chunlin; Hagen, Bjarne Christian; Frette, Vidar; Rudich, Yinon (Peer reviewed; Journal article, 2020)
      The possible use of organic particle emissions as indicators of smoldering fires at low temperatures (early stages, <150 °C) is explored in laboratory experiments. Samples consisting of wood pellets were heated under ...
    • Fast moving smoldering fronts in thin liquid fuel films dispersed on inert porous media 

      Erland, Sveinung; Meyer, Runald Walter; Hagen, Bjarne Christian (Peer reviewed; Journal article, 2022)
      An experimental study of smoldering in thin layers of pyrolysis oil on an inert substrate of calcium silicate boards has been conducted. The smoldering fronts propagated with velocities up to 0.4 mm/s, which is significantly ...
    • Flame heights and charring on a particle board – An experimental study 

      Karyaparambil, Dheeraj Dilip; Erland, Sveinung; van Hees, Patrick; Frette, Vidar; Hagen, Bjarne Christian (Peer reviewed; Journal article, 2022)
      Vertically oriented particle-board samples were exposed to external venting flames to study the fire spread and charring behaviour along a timber façade. Variation in flame height and the height, volume, area, density, and ...
    • From smoldering to flaming fire: Different modes of transition 

      Hagen, Bjarne Christian; Meyer, Anita Katharina (Journal article; Peer reviewed, 2021)
      Transition from smoldering to flaming fire in cotton is investigated experimentally for five different sample sizes. Two different modes of transition are identified: early and late transition. Early transition to flaming ...
    • Lip-height effect in diffusive pool fires 

      Kolstad, Einar Arthur; Hagen, Bjarne Christian; Frette, Vidar; Krause, Ulrich (Peer reviewed; Journal article, 2021)
      A freeboard, lip height, from the container rim to the fuel surface affects the mass-loss rate of a pool fire. Experiments where heptane was burned in circular containers with diameter 10, 20 and 30 cm have been conducted. ...
    • Skin temperatures of a pre-cooled wet person exposed to engulfing flames 

      Log, Torgrim (Journal article; Peer reviewed, 2017)
      In a television show, a wetted bare-skinned person slid through engulfing kerosene pool fire flames. The 0.74 s flame exposure resulted in pain and light sun burns. The heat and mass transfer involved in this dangerous ...
