Accurate prediction of the macroscopic flow parameters needed to describe flow in porous media relies on a good knowledge of flow field distribution at a much smaller scale-in the pore spaces. The extent of the inertial effect in the pore s...
Bridging Effective Stress and Soil Water Retention Equations in Deforming Unsaturated Porous Media: A Thermodynamic Approach [0.03%]
变形非饱和多孔介质中有效应力与土水特征曲线的热力学统一理论研究

T G Tranter et al.
Hysteresis in the saturation versus capillary pressure curves of neutrally wettable fibrous media was simulated with a random pore network model using a Voronoi diagram approach. The network was calibrated to fit experimental air-water capi...
Evaluating the Impact of the Covariance of the Friction and Potential Gradient on Describing the Infiltration Process [0.03%]
摩擦力和势能梯度的协方差对描述入渗过程的影响评估
