Spreading of Oil Spilled under Floating Broken Ice
Publication: Journal of Hydraulic Engineering
Volume 123, Issue 8
Abstract
A numerical model is developed to simulate the spreading of oil under, through, and over a broken ice cover floating on calm water. The oil spreading under the broken ice cover is modeled by modifying the spreading equations for oil under solid ice. Oil seepage through the broken ice is modeled as simple porous media flow. The oil spreading at the water surface near the top ice surface is modeled by considering the interfacial tension and viscous forces. The transport processes are interconnected through mass conservation during numerical computations. The results are compared with data from new experiments conducted in this study as well as experimental data from a previous study. Both axisymmetrical and unidirectional spreading are considered. The simplified model presented here agrees reasonably well with the observed data. The study provides new insight into how to model the problem of spreading when oil is released under a broken ice cover.
