多孔介质中流体流动的数值模拟
Numerical modeling of fluid flow through porous media (Modelowanie numeryczne transportu plynow przez osrodki porowate)
摘要：
本论文的目的是提出和分析两个特殊的问题，在多孔介质中的流动。其中第一个与多孔建筑材料的饱和过程有关。最近，M。Küntz和P. Lavalée利用这一过程的计算机模型得出结论，反常扩散假设是正确的。在这篇论文中，我提出了另一种解释，没有提到任何异常扩散的结果。论文的第二部分是对多孔介质中的流动--一个非常有趣的表征输运的物理宏观变量--弯曲度的数值分析。(in波兰文）
英文摘要：
The aim of the thesis is to present and analyze two particular problems of transport in porous media flow. The first of them is related to the process of saturation of porous building materials. Recently, M. Küntz and P. Lavalée, using a computer model of this process, have concluded that the anomalous diffusion assumption is correct. In this thesis I present an alternative explanation of this results without any refer to anomalous diffusion. The second part of the thesis covers the numerical analysis of the tortuosity of the flow -- one of a very interesting physical macroscopic variables characterizing transport in porous media.
