论文摘要
提高多孔培养基中异质性的影响对于宏观流动预测至关重要，并在能源和环境环境中广泛应用。在这项研究中，我们使用渐近分析和数值模拟的组合来得出具有垂直异质性的多孔培养基的上流流特性的表达式。然后，我们使用这些高扫描的表达式来描述含水层的动态泛滥，其中经典的Buckley-Leverett配方被修改以说明异质性。特别是，我们表明异质性可以显着改变洪水速度，并讨论这些结果在二氧化碳隔离的情况下的含义。
Upscaling the effect of heterogeneities in porous media is crucial for macroscopic flow predictions, with widespread applications in energy and environmental settings. In this study, we derive expressions for the upscaled flow properties of a porous medium with a vertical heterogeneity, using a combination of asymptotic analysis and numerical simulations. Then, we use these upscaled expressions to describe the dynamic flooding of an aquifer, where the classic Buckley-Leverett formulation is modified to account for heterogeneities. In particular, we show that heterogeneities can modify flooding speeds significantly, and we discuss the implications of these results in the case of carbon dioxide sequestration.
