摘要:
针对库区地面输油管道发生泄漏后油品流散行为的不确定性,建立了地面油品泄漏流散的三维CFD仿真模型,模拟了不同管道运行压力和不同泄漏孔径下油品在地面上的流散过程,得到了油品扩展速度关于泄漏流量的关系式和流散面积关于管道压力、泄漏孔径、流散时间的偏微分方程组。结果表明:流散面积随管道压力增大呈线性函数增大;流散面积随泄漏孔径呈三次函数变化,先减小后增大;在泄漏的开始阶段,流散面积随泄漏时间的变化随管道压力呈线性增长,在扩展达到稳定时,扩展速度随泄漏流量呈指数函数增大。
Abstract:
Aiming at the uncertainty of oil spread behavior after leakage of ground oil pipeline in oil depot, a three-dimensional CFD simulation model for the spread of leaking oil on the ground was developed. The spread processes of oil on the ground under different operating pressures and leakage hole diameters of the pipeline were simulated, and the relationship between the oil spread velocity and leakage flow rate was obtained, as well as the partial differential equations of the spread area with respect to the operating pressure, the leakage hole diameter and the spread time. The results showed that the spread area increases linearly with the increase of the operating pressure, and it presents a cubic function with the leakage hole diameter, which firstly decreases and then increases. In the initial stage of leakage, the spread area increases rapidly with the increase of the leakage time and the operating pressure, and when the expansion reaches the stable stage, the spread velocity increases exponentially with the leakage flow.
