An Impact of Sudden Ventilation in a Compartment Involving Crib Fire

Abstract

n experimental study has been conducted, in a cubical compartment having internal dimensions of 4.0 m length by 4.0 m width by 4.0 m height, to explore the impact of sudden door opening on the burning behavior of burning cribs. Several parameters were measured, such as the mass loss rate, the gas temperature, the centerline flame temperature, the intensity and distribution of heat flux within the compartment boundaries and the compartment pressure. The experimental results indicated that the sudden door opening has a significant impact on the mass loss rate of the crib. As the time of sudden door opening provided to the compartment increases, the peak mass loss rate decreases. The maximum increase in the mass loss rate was 86%, 116% and 154% for Test B, Test C and Test D, respectively. The compartment pressure, gas temperature, flame temperature and heat flux have significant increase due to sudden door opening; however, the heat flux at lower zone has seen a steep decrease.
