Experimental Study of the Effect of Ceiling Vent on Fuel Mass Loss Rate

Abstract

A series of experiments on heptane pool fires were conducted in a compartment with a horizontal ceiling vent, focusing on the effect of the size of vent and horizontal distance between vent and fire source on heptane pool average mass loss rate. Significantly positive correlations were found between the mass loss rate per area of pool fire and the area of ceiling vent, and negative correlated with relative distance. And the mass loss rate per area of pool fire remained relatively constant when (Av /S)/(L/H) was below a critical value C.
