This note presents a simulation method for investigating the relationship between porosity and particle size distribution in porous media characterization. The method simulates particle packing based on particle size distributions, incorporating descent and collision rules to mimic the natural deposition process while minimizing boundary-induced porosity distortions. By systematically varying the mean particle size and standard deviation, multiple packed structures are generated, and their corresponding porosities are calculated. This approach offers a flexible and scalable tool for exploring the impact of particle size distribution on porosity, providing both qualitative and quantitative insights into porous media properties.

Generalization of the van der Waals equation for anisotropic fluids in porous media
多孔介质中各向异性液体的广义van der Waals状态方程由两项组成。一项是基于标度粒子理论得到的无规多孔介质中硬球柱的状态方程。另一项是用分子间吸引力的平均值表示的。所得方程用于研究气液两相流动。分子系统的相变行为取决于分子形状的各向异性，分子间吸引力的各向异性，研究表明，各向异性相是由分子间相互吸引作用的各向异性和分子形状的各向异性共同作用形成的，分子形状的各向异性使多孔介质的孔隙率和孔隙率发生变化，从而使多孔介质的孔隙率和孔隙率发生变化。相图的温度和密度。吸引相互作用的各向异性使各向同性相和各向异性相之间的共存区域明显变宽，并将其移到低密度和高温度的区域。结果表明，对于足够长的球柱，液-气相变完全局限在相变区域内。对于所有考虑的情况，孔隙率的降低使相图移动到较低密度和较低温度的区域。
