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

    Torero, Jose L (Springer, 2004-05)

    This study is aimed at developing a predictive capability for uncontrolled compartment fires which can be “steered” by real-time measurements. This capability is an essential step towards facilitating emergency response ...
  • Sensor-Linked Simulation for Emergency Response 

    Fraser-Mitchell, Jeremy; Koo, Sung-Han; Welch, Stephen (Human Behaviour in Fire, 2009-07)
    The FireGrid project defines a vision whereby computational fire simulation tools are linked to real-time information derived from sensors in a building, providing potentially valuable information to an end user in terms ...
  • Sensor-steered fire simulation 

    Koo, Sung-Han; Fraser-Mitchell, Jeremy; Welch, Stephen (Elsevier - Fire Safety Journal, 2010)
    A sensor-linked modelling tool for live prediction of uncontrolled compartment fires, K-CRISP, has been developed in order to facilitate emergency response via novel systems such as FireGrid. The modelling strategy is ...
  • 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 ...

  • 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 ...
