Abstract
A one-dimensional transient heat conduction mathematical model is developed to predict the mass loss rate of a pool fire composed of three layers of metal wool - oil, oil and water. The structure of the oil-wool (porous) media is complex due to its irregular shape. The conduction heat transfer equation with appropriate boundary condition is solved by a finite volume method. The thermo-physical properties of the porous media are calculated by using a weighting average of solid and liquid phases. The computational model is first validated with experimental data available in the literature at steady state condition for a slick of oil on a water bed with varying oil slick thickness (Torero, Jose L., et al. Spill Science & Technology Bulletin 8.4, 2003.) Additional simulations are performed to analyze the effect of the conductive porous media. The results show that the presence of conductive porous media enhance the regression rate especially for thin initial fuel layer thickness. The mathematical model has been extended to predict the mass loss rate of large scale pool fires. The model can serve as a predictive tool to analyze in-situ burning of oil layer on sea surface, caused by oil spill accidents, using a metal wool blanket.
