建立了一个多相溢油模型，用于模拟海洋环境中意外溢油的后果。同时计算六个状态变量：水面上的浮油厚度;水柱中溶解、乳化和颗粒状油相的浓度;以及底部沉积物中溶解和颗粒状油相的浓度。一个一致的欧拉方法应用于整个模型，浮油厚度计算使用层平均的Navier-Stokes方程，并在水柱中的油相的输送的对流扩散方程。动力学项的开发，以控制变量之间的油质量交换。使用测试用例、数据和其他模型验证了控制方程。该模型是有用的短期和长期预测的溢油动态和命运，包括应用的石油战斗元素，如化学分散剂和繁荣。
A multiphase oil spill model has been developed to simulate consequences of accidental oil spills in the marine environment. Six state variables are computed simultaneously: an oil slick thickness on the water surface; concentration of dissolved, emulsified and paniculate oil phases in the water column; and concentration of dissolved and paniculate oil phases in the bottom sediments. A consistent Eulerian approach is applied across the model, the oil slick thickness is computed using the layer-averaged Navier-Stokes equations, and for transport of the oil phases in the water column the advection-diffusion equation is employed. The kinetic terms are developed to control the oil mass exchange between the variables. The governing equations are verified using test cases, data and other models. The model is useful for short and long-term predictions of the spilled oil dynamics and fate, including application of the oil combating elements, such as chemical dispersants and booms.
