  • The Piloted Transition to Flaming in Smoldering Fire Retarded and Non-Fire Retarded Polyurethane Foam 

    Putzeys, Olivier; Fernandez-Pello, Carlos; Rein, Guillermo; Urban, David (Wiley InterScience - Fire and Materials, 2008-12)
    The piloted transition from smoldering to flaming, though a significant fire safety concern, has not been previously extensively studied. Experimental results are presented on the piloted transition from smoldering to ...
  • 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 role of secondary char oxidation in the transition from smoldering to flaming 

    Putzeys, Olivier; Bar-Ilan, Amnon; Rein, Guillermo; Fernandez-Pello, Carlos; Urban, David (The Combustion Institute, 2006-08)
