论文摘要
通过多孔介质的流动很大取决于边界条件，通常认为是静态的。在这里，由于肿胀和侵蚀，我们考虑了培养基的变化，并扩展了现有的晶格玻璃体模型，以包括两者。我们研究两个边界条件：恒定压降和恒定流速。对于恒定的流速，稳态仅取决于侵蚀动力学，而对于恒定压力下降，它也取决于肿胀的时间尺度。我们分析肿胀和侵蚀之间的竞争，并确定肿胀或侵蚀占主导地位的政权之间的过渡。
The flow through a porous medium strongly depends on the boundary conditions, very often assumed to be static. Here, we consider changes in the medium due to swelling and erosion and extend existing Lattice-Boltzmann models to include both. We study two boundary conditions: a constant pressure drop and a constant flow rate. For a constant flow rate, the steady state depends solely on the erosion dynamics while for a constant pressure drop it depends also on the timescale of swelling. We analyze the competition between swelling and erosion and identify a transition between regimes where either swelling or erosion dominate.
