摘要
水下原油管道泄漏难以被发现和预测,这对原油泄漏事故处理提出了很大挑战。文章基于FLUENT软件,分析当(河底/海底)水下原油输送管道发生泄漏时,原油在上浮过程中在水体内部的扩散过程,并研究了在无风或有风条件下,泄漏原油到达水面时的扩散形状和扩散规律。结果表明:在本文的研究条件下,当泄漏油品到达水体表面时,在无风条件下,原油在水体表面呈圆形,随着时间发展逐渐向周围扩散,由圆形变为椭圆形,最终在不同方向呈现的破碎、分离形状发生更大范围的扩散;在有风条件下,原油扩散主要表现为随着风的方向发生漂移,原油形状基本保持不变。
It is difficult to detect and predict underwater crude oil pipeline leakage,which poses a great challenge to the handling of crude oil leakage.Based on FLUENT software,this paper analyzes the diffusion process of crude oil inside the water body during its upward flotation when a leakage occurs in a(river bottom/seabed)underwater crude oil transportation pipeline.And it studies the diffusion shape and diffusion law of the leaked crude oil when it reaches the water surface under windless or windy conditions.The results show that:under the research conditions of this paper,when the spilled oil reaches the surface of the water body,the crude oil is round on the surface of the water body,and gradually spreads to the surrounding area with the passing of time,and changes from a round shape to an oval shape,and ultimately a larger range of diffusion occurs in the broken and separated shape presented in different directions under the windless condition;and under the windy condition,the diffusion of the crude oil is mainly displayed as a drift along with the direction of the wind,and the shape of the crude oil remains largely unchanged.
