摘要

提出了含水层非水流体运移的数学模型。该模型描述了多孔介质中的两相流动、温度场动力学和系统中的输运:水相-有机相-多孔材料。采用随机确定性方法对模型进行了数值实现。采用确定性方法描述了多孔介质中的压力场、液相与多孔材料之间的质量传递、热传导。液体的两相过滤和对流的热量和质量输运用游荡流线随机描述。对非水污染物的迁移羽毛进行了分析。模拟了非定常传热传质引起的两相流流体动力不稳定发展。

Modeling of underground water contamination by non aqueous liquids

The mathematical model of non-aqueous liquid migration in aquifer is presented. The model includes description of the two-phase flow in porousmedia, dynamics of temperature field and transport in the system: aqueous phase organic phase porous material. Stochasticdeterministic approach has been used for numerical realization of the model. Deterministic methods were used for description of the pressure field in the porous media, mass transport between the liquid phases and porous material, heat conduction. The two phase filtration of the liquids and the convective heat and mass transport were described stochastically with wandering stream lines. Analysis of non-aqueous pollutants migration feathers is presented. Two-phase flow hydrodynamic instability development due to unsteady heat and mass transfer has been simulated.
