• 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 ...
    • 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 ...
