Abstract:

A model was developed for oil slick elongation as a result of entrainment and resurfacing (wind shear). A series of model runs was performed to investigate the influence of oil properties oil type and wind speed on the elongation.

Purpose:

To investigate the influence of certain parameters on the elongation process in order to understand when dispersants would be beneficial and when not.
