    This paper develops a novel modelling approach for ventilation flow in tunnels at ambient conditions (i.e. cold flow). The complexity of full CFD models of low in tunnels or the inaccuracies of simplistic assumptions are ...
  • Calculation Methods for the Heat Release Rate of Materials of Unknown Composition 

    Biteau, Hubert; Steinhaus, Thomas; Simeoni, Albert; Schemel, Christopher; Marlair, Guy; Bal, Nicolas; Torero, Jose L (International Association for Fire Safety Science, 2008-09)
    The Heat Release Rate (HRR) is a critical parameter to characterise a fire. Different methods have been developed to estimate it. The most widespread techniques are based on mass balance. If the heat of combustion of the ...
  • Caractérisation de la fraction volumique et de la température des suies d'une flamme de diffusion établie en micropesanteur 

    Fuentes, Andres; Legros, Guillaume; Joulain, Pierre; Vantelon, Jean-Pierre; Torero, Jose L (Congrès Français de Mécanique, 2005-08-29)
    The soot has a dominant radiative role in microgravity diffusion flames. In fact, the radiative losses are particularly important in the trailing edge of the flame, where the combustion products, especially the soot, ...

    Torero, Jose L; Olenick, Stephen M; Garo, Jean P; Vantelon, Jean P (Elsevier, 2003)
    The burning rate of a slick of oil on a water bed is characterized by three distinct processes, ignition, flame spread and burning rate. Although all three processes are important, ignition and burning rate are critical. ...
