One approach hinges on the numerical solution of Stokes equations, while the other is based on the Johnson-Koplik-Dashen (JKD) universal scaling theory of viscous frequency-dependent flow [D.~L. Johnson, J.~Koplik, and R.~Dashen, \\emph{Theory of dynamic permeability and tortuosity in fluid--saturated porous media}, Journal of Fluid Mechanics \\textbf{176} (1987), 379--402.] and the method of maximal inscribed spheres.\n  JKD steady-flow simulatio"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1311.3988","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
