Abstract
Quantitative dispersion data, generated on a laboratory scale, using different experimental set-ups and approaches, in order to fill in different blanks in modelling the dispersion process. Main variables investigated are oil properties and dispersant concentration(/presence) in relation to; surface oil entrainment, oil droplet breakup and oil-sediment interaction.
Purpose
Generate data for modelling natural and chemical dispersion of spilled surface oil.
