  • The Risk Imposed by Fire to Buildings and How to Address It 

    Torero, Jose L (Springer, 2004-05)
    The history of fire science originates in the desire to enhance destruction of infrastructure by means of fire. Many of the basic principles of fire growth and the behaviour of structures in fire were developed within the ...

  • The Severity of Smouldering Peat Fires and Damage to the Forest Soil 

    Rein, Guillermo; Cleaver, Natalie; Ashton, Clare; Pironi, Paolo; Torero, Jose L (Journal Catena (Elsevier), 2008-08)
    Smouldering wildfires propagate slowly through surface and subsurface organic layers of the forest ground and severely affect the soil, producing physical, chemical and biological changes. These effects are caused by the ...
  • Small-Scale Forward Smouldering Experiments for Remediation of Coal Tar in Inert Media

    This paper presents a series of experiments conducted to assess the potential of smouldering combustion as a novel technology for remediation of contaminated land by water-immiscible organic compounds. The results from ...
  • Smoke buildup and light scattering in a cylindrical cavity above a uniform flow 

    Upadhyay, Rochan; Ezekoye, Ofodike (Elsevier, 2005)
    In this study, we use computational fluid dynamics (CFD) and aerosol dynamics modeling to investigate the buildup of smoke and light scattering in a cylindrical cavity geometry, considered to be an idealized representation ...
  • Smoldering - The Fire Scenario 

    Torero, Jose L (2000)
    There are certain fire initiation scenarios that are particularly common, one of great significance is a fire initiated from the ignition of a porous fuel. Nearly 40% of the deaths due to fire can be traced to cigarette induced ...
  • Smouldering Combustion Phenomena in Science and Technology 

    Rein, Guillermo (International Review of Chemical Engineering IRECHE - Praise Worthy Prize, 2009-01)
    Smouldering is the slow, low-temperature, flameless form of combustion of a condensed fuel. It poses safety and environmental hazards and allows novel technological application but its fundamentals remain mostly unknown ...
  • Soot Volume Fraction Measurements in a Three-Dimensional Laminar Diffusion Flame established in Microgravity 

    Legros, Guillaume; Joulain, Pierre; Jean-Pierre, Vantelon; Fuentes, Andres; Bertheau, Denis; Torero, Jose L (Taylor and Francis Ltd, 2005-05-03)
