Abstract

The heat feedback of flame plumes is a main form of energy transfer and a significant contributor to fire growth and spread. The paper introduces the case of heptane pool fires in open spaces. A corresponding formula is proposed along with the simplified model of plume heat feedback based on the analysis of heat balance equations of pool fires. A hybrid CFD model of heptane pool fire simulation methodology is used to study the fire characteristic parameters and plume heat feedback effects in the combustion process of pool fires. The results suggest that plume heat radiation and convection effects cause about 53% and 37% of the total mass loss rate in the combustion process of 1m2 heptane pool fire and thus that they play an important role on the occurrence and development of liquid fires.
