A Tractable Solution for Engineering Calculations on a Full Scale Enclosure Fire

Abstract : The phenomenological analysis of backdraft, experimentally observed in enclosure fire, has been made with the help of CFD simulation. The current numerical simulations include the initial mixing as a gravity current after opening of the enclosure, the ignition, spreading of flame in the enclosure, the external fireball, and subsequent decay. Histories of the calculated relative pressure pulse and temperature peak are compared with the measured ones. The predicted pressure and temperature levels agree quantitatively with the experimental data. Globally, Large Eddy Simulation combined with an EDC combustion model shows the feasibility for simulations of transient combustion events occurring in an enclosure filled with a mixture of fuel in air.
