Fecha de publicación: | 15-dic-2021 | Editor: | Elsevier | Citación: | Ocean Engineering 242: 110096 (2021) | Resumen: | We present a Compositional Eulerian model to forecast the evolution of oil spills in the sea. The model allows studying the fate of not only the oil concentration but also of each component (e.g., volatile, non-volatile, water in the oil). Therefore, the problem is formulated as a conservation equation for each component, plus an equation to estimate the age of the oil, which allows us to assess weathering processes (e.g., evaporation, natural dispersion, emulsion) and the associated changes in oil properties. We describe an efficient implementation, using second order numerical schemes for advection and nonlinear diffusion terms, to reduce numerical diffusion. We perform numerical experiments, based on real and synthetic cases, to illustrate and validate the capabilities of our model to forecast the evolution of oil spills and to perform environmental risk analysis in the case of a potential accident. | Versión del editor: | https://doi.org/10.1016/j.oceaneng.2021.110096 | URI: | http://hdl.handle.net/10261/255584 | DOI: | 10.1016/j.oceaneng.2021.110096 | ISSN: | 00298018 |
