Measurement of Vertical Turbulent Dispersion and Diffusion of Oil Droplets and Oiled Particles

摘要

The study is intended to develop mathematical relations for the turbulent dispersion of spilled oil and oiled particles in the sea. The laboratory experiments were conducted to provide a basis for the mathematical relations with empirical data on oil dispersion and oil-SPM interaction. Empirical relations and data were obtained for the following processes: (a) break-up of surface oil films into droplets, and intrusion of droplets in the water column, due to breaking wave effects; (b) break-up of submerged oil parcels (submerged leak) into droplets due to turbulence in the seawater; (c) interaction between oil droplets and SPM. The empirical relations can be used in mathematical models with given hydrodynamic conditions and breaking wave statistics.
