以中砂和0号柴油为研究对象,通过室内物理模拟试验以及构建的描述柴油在包气带运移的多相流动力学模型,定性定量研究了柴油泄漏后在非饱和带内的运移分布特征。结合物理模拟试验及数学模拟,描述柴油泄漏进入巾砂介质中的过程,得到毛细带以上的残余油区及毛细带至地下水面的聚集油区的油相在非饱和带的分布特征。结果表明,利用室内二维渗流装置,可较好揭示柴油渗漏后在地下环境中运移过程。
Taking Zhongsha and No.0 diesel as the research object, through the indoor physical simulation test and the multi-phase flow dynamics model which describes the migration of diesel in the aeration zone, the migration distribution in the unsaturated zone after diesel oil leakage was qualitatively and quantitatively studied feature. Combined with physical simulation and mathematical simulation, the process of diesel leaking into towel media is described, and the distribution characteristics of oil phase in the unsaturated zone are obtained from the residual oil zone above the capillary zone and the concentrated oil zone from the capillary zone to the groundwater surface. The results show that the use of indoor two-dimensional seepage device, can better reveal the leakage of diesel in the underground environment after the migration process.
