A comparison of oil weathering model equations and application to Douglas Channel / by A. van der Baaren, Y. Wu, and C. Hannah. : Fs97-18/316E-PDF

"The purpose of this work was to develop software tools to provide a basis for understanding commonly used oil weathering models. We evaluated computational algorithms that are used by three popular oil weathering models, and similar algorithms that are used by other researchers, to see how sensitive the algorithms/models were to variable environmental conditions and to gather information on whether the models typically produce similar results. We computed the weathering evolution, under constant and variable environmental conditions, of dispersion, release/spreading, evaporation, emulsification (water content), oil density, and oil viscosity for a hypothetical spill, and we compared the results for the different models’ algorithms. We applied the algorithms to a second hypothetical spill. The second spill was of Cold Lake Bitumen in Douglas Channel. We found that none of the algorithms produced realistic results when using a time varying wind speed as input probably because they were developed under conditions of constant wind speeds. Finally, this work is not a definitive description of the expected evolution of the properties of diluted bitumen in Douglas Channel"--Abstract, p. xi.
