A compositional Eulerian approach for modeling oil spills in the sea

We present a Compositional Eulerian model to forecast the evolution of oil spills in sea. The allows studying fate not only concentration but also each component (e.g., volatile, non-volatile, water oil). Therefore, problem is formulated as conservation equation for component, plus an estimate age oil, which us assess weathering processes evaporation, natural dispersion, emulsion) and associated changes properties. describe efficient implementation, using second order numerical schemes advection nonlinear diffusion terms, reduce diffusion. perform experiments, based on real synthetic cases, illustrate validate capabilities our environmental risk analysis case potential accident.
