For the first time, a model derived strictly from physics is proposed to show that the flow instability under finite amplitude disturbance leads to turbulent transition. The proposed model is named as \"energy gradient method.\" It is demonstrated that it is the transverse energy gradient that leads to the disturbance amplification while the disturbance is damped by the energy loss due to visc","authors_text":"Hua-Shu Dou","cross_cats":["physics.class-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2006-07-02T14:44:21Z","title":"Physics of Flow Instability and Turbulent Transition in Shear Flows"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"physics/0607004","kind":"arxiv","version":5},"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":"sha256:045338b4bb472b302af7a22bc2cec6f09468c0605ae9bc037f89cf624fee4310","target":"record","created_at":"2026-05-18T00:12:57Z","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":"b7e4229f8bc51af96ba5f06105e119f8b139bb22d0a3e2e7206c8087d8ca73b8","cross_cats_sorted":["physics.class-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2006-07-02T14:44:21Z","title_canon_sha256":"5fe55e2ea74b92cf1013cc8862bd4c592b8a8df0e8d188248a2d68630f67d903"},"schema_version":"1.0","source":{"id":"physics/0607004","kind":"arxiv","version":5}},"canonical_sha256":"24ffe9cb298026ae10f93b255c04f6bfb1b869b21fc38c426af809808d4c3381","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"24ffe9cb298026ae10f93b255c04f6bfb1b869b21fc38c426af809808d4c3381","first_computed_at":"2026-05-18T00:12:57.442923Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:12:57.442923Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZZVxAclB3zWvJqvnJSOF3VvyRL0sb8+g2J5nJMOwx59vxTPehZEnsq0XxFkZoxQPB8hVURyAYupSPn6qSyTaDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:12:57.443613Z","signed_message":"canonical_sha256_bytes"},"source_id":"physics/0607004","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:045338b4bb472b302af7a22bc2cec6f09468c0605ae9bc037f89cf624fee4310","sha256:559fcaf15283d414149d983cb113fef6bd68426b797183d60c7214a31df74b3a"],"state_sha256":"7cbd9a2e8135bed4c514f30024ffa845dc32217ba3c6d663019526bc8ef5dc75"}
