STUDY OF WALL TEMPERATURE AND HEAT FLUX DISTRIBUTION IN FLASHOVER COMPARTMENT FIRES

  • Unique Paper ID: 146965
  • PageNo: 624-639
  • Abstract:
  • Newer construction materials and techniques are being introduced in construction industry to conserve materials and energy [21]. Conventionally, fire safety of these materials is evaluated by imposing standard time – temperature profiles during testing [6-12]. Choice of these profiles is based on the wall temperature & heat flux during real fire scenarios and it will have consequences on structural fire safety. Fire Dynamics Simulator, FDS, an appropriate and popular tool [18-22] for the fire driven flows in the built environment will be used to evaluate heat flux and temperature distribution in a 1 m3 size room for several size pan fires. Results will be compared with experiments to validate the model. Wall temperature and heat flux distribution in a standard IS 9705[7] size (3.6 x 2.4 x 2.4 m) compartment normally used for testing building materials will be studied. FDS results obtained will be compared with literature. Realistic heat flux distribution will provide more accurate boundary conditions to structural analysis resulting in improved structural fire safety.
