Melting of Ice and Formation of Lateral Cavity during In Situ Burning in Ice-Infested Waters


The ice melting and lateral cavity formation caused by in situ burning (ISB) of liquid fuels in ice-infested waters was studied in order to improve predictions on the removal efficiency of this oil spill mitigation method. For this purpose, several experimental studies were conducted to improve our understanding of the heat transfer mechanisms that cause the ice melting and lateral cavity formation. In the experimental part of the study, a variety of measurement techniques were used to study and investigate the physics of the problem. In particular, it was shown the flame heat feedback and Marangoni driven convection play a key role in melting of the ice. The findings of the experimental studies provided the required knowledge to mathematically formulate the ice melting problem. Mathematical scaling analysis of ice melting during burning of oils in the vicinity of ice was performed to create a tool to estimate the extent of melting that occurs during ISB in ice-infested waters. The lack of practical and theoretical knowledge on the ice melting during in situ burning could lead to weak estimations and unsuccessful burn operations. Since melting of ice during burning of pool fires in ice confinements has significant influence on oil spill cleanup in ice-infested waters, the results of this study are very important for successful implementation of in situ burning in Arctic regions.
