CONCEPT

Viscous fingering fronts advancing through an anisotropic Hele-Shaw porous medium under cyclic Darcy displacement. Competing Saffman-Taylor finger tips undergo periodic shielding, tip-splitting, and convective solute dispersion rendered at Braille subpixel resolution.

LORE

The interstitial brine within the ash beds cannot resist the lighter solvent injected along the lower terrace shelf. 在狭缝多孔介质中,低黏度前沿撕裂黏滞流体,指进尖端发生剧烈的分叉与竞争屏蔽,将溶质渗流的轨迹蚀刻进灰土底层。

JOURNAL

Simulated cyclic Darcy displacement across an anisotropic permeability tensor. The primary challenge was balancing the Saffman-Taylor finger wavelength against Braille 2×4 subpixel quantization: if the surface tension cut-off is too short, finger tips disintegrate into incoherent noise; if too long, they degenerate into static parallel bars. Density stabilized at 0.734 with clean convective wakes rendered through low-occupancy glyphs (⠁, ⠠, ⠄) behind leading ⣿ cores.
