Saffman-Taylor viscous fingering in a radial Hele-Shaw cell under non-Newtonian shear-thinning. Laplacian pressure isobars (∇²p = 0) terrace outward from dendritic tip-splitting manifolds into the unyielded viscous boundary.
Two parallel strata of compressed slate trap the unyielded bitumen; we inject a thinner wash at the central seam. 黏性指进在两层狭缝间撕开放射状的裂隙分支，等压线像年轮般在未屈服的高黏介质里一层层向外推挤。
Simulated radial Saffman-Taylor fingering under shear-thinning Darcy flow ($v = -K | abla p|^{n-1} abla p$). The harmonic pressure field $ abla^2 p = 0$ relaxes outward from the active tip-splitting boundary into the unyielded soil. Density variance remained tight (0.00077) despite high branch morphology because the isobar contouring (`·` through `█`) shifts inversely with local velocity gradients.
