Abstract

Experimental results on hydrocarbon pool fires are reported. Experiments on light and heavy diesel oil pool fires with diameters of 200 and 300mm were carried out. Experimental simulations were conducted to investigate the mechanisms of boilover phenomena in liquid pool fires with water sublayers. The temperatures in oil layer, water layer and vapor space were measured as the fire proceeded. Experimental examinations demonstrated that boilover only happens for heavy diesel after the fuel/water interfacial temperature has reached the boiling point of water, and that it was the violent seething of water at the interface which brought about boilover. Observations of fire behavior and instrumentation of the local temperature history in oil/water layers revealed that the hot zone is not the essential condition for boilover. A numerical model was proposed and compared with experiment results.
