  • Modelling of Structures in Fire: An Example of the Boundary Condition 

    Jowsey, Allan; Torero, Jose L; Usmani, Asif (GRUPO GIDAI, Universidad de Cantabria (Spain), 2004-10)
    The collapse of the World Trade Center Towers 1, 2 and 7 on September 11th 2001 has highlighted the need for proper understanding of the behaviour of structures in the event of a fire. A detailed analysis of the fires and ...
  • Modelling the Propagation of Forward and Opposed Smouldering Combustion 

    Rein, Guillermo; Torero, Jose L; Fernandez-Pello, Carlos (EUROTHERM, 2007-06)
    A computational study has been carried out to investigate smouldering ignition and propagation in polyurethane foam. The one-dimensional, transient, governing equations for smouldering combustion in a porous fuel are ...
