THE EFFECTS OF SURFACE PHENOMENA ON THE SPREADING OF OIL ON WATER
Models for the prediction of the spreading of oil slicks, when involving the surface tension regimes of spreading, use only the bulk properties of the spreading oil. Oils are made up of multitudes of different compounds which have different chemical and surface properties. Experiments conducted with four crude oils showed very little correlation between bulk properties and spreading behavior. Mixtures of hydrocarbons of known spreading properties were spread. Results demonstrate a direct relationship between spreading properties of the individual components and spreading behavior of the mixtures. Samples of spreading Diesel fuel were collected and different radii on the slick exhibited compositional variations along the spread. The formation of patches of thick oil, observed in many oils, but rarely taken into account in spreading models, is explained.
