论文摘要
海上漏油模型的主要重点通常放在油的最终位置，即水平运输。但是，由于当前的剪切，防风以及在表面和水柱上影响油的不同物理，化学和生物学过程，对油的垂直分布进行建模对于对水平运输进行建模至关重要。 在这项工作中，我们审查并介绍了许多影响油的垂直运输的物理过程，包括波浪夹带，液滴升高，垂直湍流混合和表面。我们旨在为读者提供足够的细节，以便能够理解和实施模型，并提供进一步阅读的参考。包括数学和数值细节，尤其是关于粒子的对流和扩散。我们还提出并讨论了一些可能有些微妙的常见数值陷阱，但可能会导致重大错误。
The main focus of marine oil spill modelling is often on where the oil will end up, i.e., on the horizontal transport. However, due to current shear, wind drag, and the different physical, chemical and biological processes that affect oil differently on the surface and in the water column, modelling the vertical distribution of the oil is essential for modelling the horizontal transport. In this work, we review and present models for a number of physical processes that influence the vertical transport of oil, including wave entrainment, droplet rise, vertical turbulent mixing, and surfacing. We aim to provide enough detail for the reader to be able to understand and implement the models, and to provide references to further reading. Mathematical and numerical details are included, particularly on the advection and diffusion of particles. We also present and discuss some common numerical pitfalls that may be a bit subtle, but which can cause significant errors.
