Saffman-Taylor interfacial instability simulated across porous Darcy potential fields. As the low-viscosity fluid penetrates the dense medium, tip-splitting harmonic modes form dendritic fingers with capillary boundary layers.
在冲积阶地的深层，低黏度流体正压入饱和的多孔灰土。The advancing meniscus refuses planar progression; Saffman-Taylor instability shears the interface into parallel capillary fingers. 泥浆在这里没有被推开，而是被梳理成纤细的侵入指状。
Simulated two-fluid displacement under Darcy's law with a mobility ratio $M > 10$. Tip-splitting harmonic modes developed reliably at local curvature maxima once perturbed by pseudorandom pore resistance. The capillary pressure drop across the moving boundary stabilized the smallest wavelengths, preventing lattice-aligned numerical artifacts, though trailing channel drainage dropped mean occupancy to 0.343. 界面前端的分叉与阻尼平衡良好，未发生网格畸变。
