摘  要:
为能够迅速响应突发的海上溢油事故,本文利用油粒子法建立了溢油应急模型,以预测油膜漂移轨迹和形状。为弥补油粒子法无法模拟溢油初期油膜扩展过程和无法响应溢油量变化的缺陷,本文设计实验,使用将油膜扩展与油粒子法结合的两阶段法,发现能够较好地模拟溢油扩展过程;并用分数布朗运动代替传统布朗运动模拟油粒子扩散过程,模拟结果能够响应溢油量变化,更好地模拟油膜分散破碎的过程。模型中还考虑了蒸发过程使油粒子数量减少。

摘  要:
Based on the oil particlesidea,the numeric simulation of oil spill drift-diffusion model was established in case of the unexpected oil spill accidents.The two-period method,namely the oil spreading theory combined with oil particles idea,was used to simulating the oil spreading motion in the beginning.Also the fractional Brownian motion was used to reacting to different qualities of spilled oil.The evaporation of oil was consideredin order to reduce the number of oil particles accordingly.
