用大量质点的运动近似海洋溢油的运动,把整个溢油看成有大量的体积很小的油块微元组成,即将溢油分为大量的质点,这些质点进行彼此独立的运动,每一质点代表一定的油量,油膜的迁移、扩展看作质点群的迁移、扩展。溢油的扩散看作质点群在湍流作用下进行的拉格朗日运动。油的蒸发、 With a large number of particle motion similar to the movement of the marine oil spill, the entire oil spill as a large number of tiny oil blocks of micro-components, the upcoming oil is divided into a large number of particles, these particles independent of each other’s movements, each The particle represents a certain amount of oil, oil film migration, expansion as the mass group migration, expansion. The proliferation of oil spills is seen as a Lagrangian movement of the mass group under turbulent flow. Evaporation of oil,
