The proposed method relies on physical mechanisms to resolve and smooth sharp unresolved flow features that may otherwise lead to numerical instability, such as shock waves and under-resolved thermal and shear layers. To that end, we devise various sensors to detect when and where the shear viscosity, bulk viscosity and thermal conductivity of the fluid do not suffice to stabilize the numerical solution. In such cases, the fluid viscosities are selectively increased to ensure the cell Peclet number is of order on","authors_text":"Jaime Peraire, Ngoc-Cuong Nguyen, Pablo Fernandez","cross_cats":["nlin.CD","physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-06-17T21:17:07Z","title":"A physics-based shock capturing method for large-eddy simulation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.06449","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":"sha256:2a2b7f81de1267eb07af1d1ab2f3d3fb97bd0cd53ae8f37fb24e11de49759fe1","target":"record","created_at":"2026-05-18T00:13:02Z","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":"17e941d4f3421a66a0714b4ce784043817d4980838f0162056e18bcc4a480c53","cross_cats_sorted":["nlin.CD","physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-06-17T21:17:07Z","title_canon_sha256":"8a1f9165a118b405245a1100258a4c1ff3e4ca9fd2a15fdec5e7bec04ee3171c"},"schema_version":"1.0","source":{"id":"1806.06449","kind":"arxiv","version":1}},"canonical_sha256":"a8303eb25492d47a8e16623d0844031b9dab8ddda2386605edce01180004cc3c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a8303eb25492d47a8e16623d0844031b9dab8ddda2386605edce01180004cc3c","first_computed_at":"2026-05-18T00:13:02.353712Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:13:02.353712Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bN/tjawwC37ru5rZgG8kD6wukOejodBcYmWmcZhiK1LPI3SQMlBf6oIuWJeBpk3rVSHiavlH6lDCzZ9gLo3iCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:13:02.354247Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.06449","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2a2b7f81de1267eb07af1d1ab2f3d3fb97bd0cd53ae8f37fb24e11de49759fe1","sha256:75ff1cdf042fa0283e50c11922ad6db05b586435ad60017692f03b28f02f6dec"],"state_sha256":"d24b5945b15028dc0296ea57127c95dc10710167e0ed854e0b27c90a92b7ab19"}
