海洋石油污染已成为当今严重的全球性环境问题之一,得到了愈来愈多的关注.石油进入水域后的蒸发过程,虽然是研究水体对石油物理自净能力的重要内容,但其精确的预报方法至今在国内外尚未解决.本文基于湍流模式理论及Stefan流的概念,提出了多组分有蒸发的湍流模型,用来模拟石油的蒸发规律.数值模拟的结果与物理模型试验资料进行了对比,得到了比较满意的结果.
Offshore oil pollution has become one of the most serious global environmental problems and has drawn more and more attention.Evaporation process after entering the water area is an important part of studying the physical self-purification ability of petroleum, but its accurate prediction The method has not been solved at home and abroad so far.Based on the turbulence model theory and Stefan flow concept, a multi-component evaporative turbulence model is proposed to simulate the evaporation law of petroleum.The numerical simulation results are compared with the physical model test data , Got a more satisfactory result.
