Unlike previous work, the turbulent base state velocity profile proposed here requires only a specification of a flowrate or pressure drop, and no a posteriori choice of parameters. Moreover, the base state contains sufficient detail such that it allows for instability due to a viscosity-contrast mechanism (which turns out to be dominant) as well as instability due to a critical-layer-type mechanism, and it is validated against the experimental and nu","authors_text":"Lennon \\'O N\\'araigh, Omar Matar, Peter Spelt, Tamer Zaki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2009-08-07T11:09:16Z","title":"Interfacial instability in turbulent flow over a liquid film in a channel"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0908.1022","kind":"arxiv","version":2},"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":"sha256:9302e3cdaec02397e90bf699343e3fbd81917e906ff4fb3b4fc3aa0ced9def93","target":"record","created_at":"2026-05-18T00:56:53Z","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":"422bf5465aebe9bbdc770bc985e8d0d78cda83932b6b687a726e01c4e1fa2d5d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2009-08-07T11:09:16Z","title_canon_sha256":"23533479f5af33c0c3f93804d9ffd7ca46e4619dd99d2e422b324cbd1d6c5428"},"schema_version":"1.0","source":{"id":"0908.1022","kind":"arxiv","version":2}},"canonical_sha256":"d4844bcd042fcb11d903db1a9109932eaa64dc9ff85ed9a1281abd968414ec59","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d4844bcd042fcb11d903db1a9109932eaa64dc9ff85ed9a1281abd968414ec59","first_computed_at":"2026-05-18T00:56:53.121134Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:56:53.121134Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eoaJOdydC/6gZT9eDl7GM1yAn1GMIj3n12b4mgMyDT3Rg6fu5yH/HbTJzJdFdR9c2iarYi1NgKTCjS6exmhlAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:56:53.121974Z","signed_message":"canonical_sha256_bytes"},"source_id":"0908.1022","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9302e3cdaec02397e90bf699343e3fbd81917e906ff4fb3b4fc3aa0ced9def93","sha256:8bb24c26f37b87512ce48b86051483023785a18ad36cad6d22c19f34d7f25424"],"state_sha256":"d3f2be7ef420987f87aaba65d1445749a959b380f1a70bfe3f54c381a85e067e"}
