Physically, the perfect-slip stripes model the parallel grooves where a large gas cushion forms between fluid and solid wall, giving rise to slippage at the gas-liquid interface. The potential of the boundary element method (BEM) in dealing with mixed no-slip/perfect-slip boundary conditions is exploited to systematically calculate the mobility tensor for different particle-to-wall relative positions and for different p","authors_text":"Carlo Massimo Casciola, Daniela Pimponi, Mauro Chinappi, Paolo Gualtieri","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2017-03-30T10:38:27Z","title":"Mobility tensor of a sphere moving on a super-hydrophobic wall: application to particle separation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.10396","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0b91b3929724352e670211c333f36bb82869cdabb9ea1a55bf57d1353f71bd8a","target":"record","created_at":"2026-05-18T00:47:37Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"8f26ac55abb896a977c09d434b5122c4e5adad7e6cbce5d65549d6ecf586c576","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2017-03-30T10:38:27Z","title_canon_sha256":"47370f8bfdfa32185009da3c96352b46e5c171f7d8b93d53a98e4de8618bed0b"},"schema_version":"1.0","source":{"id":"1703.10396","kind":"arxiv","version":1}},"canonical_sha256":"b37e0d17bdbe29b000147a57b814b4d2979a78f7039e779ada60abfeba229674","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b37e0d17bdbe29b000147a57b814b4d2979a78f7039e779ada60abfeba229674","first_computed_at":"2026-05-18T00:47:37.111041Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:47:37.111041Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iSYdJ3p7c0JHCMAaCB+6dl87J0AciBBc5+1tsEA0+KQ2i6jmWDtASfn6E7Rsq5iY6fn/HPGjxCd8JLpNFPASAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:47:37.111565Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.10396","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0b91b3929724352e670211c333f36bb82869cdabb9ea1a55bf57d1353f71bd8a","sha256:06e33e979b004a519479a31c64667d81a1149cd011243679fdfd6fe6b86ed45f"],"state_sha256":"a32e545b05f8c3b7faf789cd7f7fa6f4f7f48508145f4c314330939eaeb46ae6"}
