Four different, standard turbulence models are tested in a model geometry based on pre-operative CT images of a selected obstructive sleep-apnea syndrome (OSAS) patient. The results show only minor differences between them. Furthermore, the turbulence models do not give significantly different results than a laminar flow model. Thus, the main conclusion is that effects of turbu","authors_text":"Are Johan Simonsen, Bernhard M\\\"uller, Elin Aasgrav, Sverre Gullikstad Johnsen","cross_cats":["physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.med-ph","submitted_at":"2017-06-08T13:08:26Z","title":"CFD simulations of turbulent flow in the human upper airways"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.02565","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:a30795933a477ff6f11682b2727a79cd9271d46f694b99742cfd69e03219521a","target":"record","created_at":"2026-05-18T00:42:45Z","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":"7fe3b6318c9ae8e6967ab378381734e7cba9333e8941139dc5073e891a797e19","cross_cats_sorted":["physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.med-ph","submitted_at":"2017-06-08T13:08:26Z","title_canon_sha256":"0ffb7d8adb854e0a3a30aadba94e73d02e7853e8fa23a7813c9311ec7ff16b0a"},"schema_version":"1.0","source":{"id":"1706.02565","kind":"arxiv","version":1}},"canonical_sha256":"f88515765be4f53e5d4caea81f8fc834179570a0f99132433425db59880638f6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f88515765be4f53e5d4caea81f8fc834179570a0f99132433425db59880638f6","first_computed_at":"2026-05-18T00:42:45.140155Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:42:45.140155Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZxvvbEahHmgw+fbRfzjvbXHkJR50VHYzAJ5F5D8Nlmm0oVFHwpBshg1EjYicM2H8KH1SpNHKhHuLjQb/egrvDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:42:45.140737Z","signed_message":"canonical_sha256_bytes"},"source_id":"1706.02565","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a30795933a477ff6f11682b2727a79cd9271d46f694b99742cfd69e03219521a","sha256:e3bccf144f7567675777ef5dd924e2c55533d2e464d264d5496878173d19e58f"],"state_sha256":"33a8280341efbc7d3168c2d01dd1ce3b1caf546d0107e9e4aaef24a7504b17ab"}
