Existing closures for pressure effects in terms of A are unable to reproduce one important statistical role played by the anisotropic part of the pressure Hessian, namely the redistribution of the probabilities towards enstrophy production dominated regions. As a step towards elucidating the required properties of closures, we study several synthetic velocity fields and how well they reproduce anisotropic pressure effe","authors_text":"Carlos Rosales, Charles Meneveau, Emmanuel Leveque, Francesco Taddia, Huidan Yu, Laurent Chevillard","cross_cats":["nlin.CD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2011-06-06T12:34:25Z","title":"Local and nonlocal pressure Hessian effects in real and synthetic fluid turbulence"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1106.1046","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":"sha256:94771ae8fffb370ce1e3192bc2153cd8fdb874a6795dac3a168f1e5f2040581d","target":"record","created_at":"2026-05-18T04:12:33Z","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":"db22bb97007c6248e402c6c4637af9c83bb6a312a4778b2726d28e35ade3cb87","cross_cats_sorted":["nlin.CD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2011-06-06T12:34:25Z","title_canon_sha256":"d11547e103ebeae2187aabeaee0dd372cedbfd31c99e206a84dc2b630ccb5e7c"},"schema_version":"1.0","source":{"id":"1106.1046","kind":"arxiv","version":2}},"canonical_sha256":"d96eeb87521f8c59b89d4c15c70ccb6f5bb0367c8b8a6ed4529664b97812e58a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d96eeb87521f8c59b89d4c15c70ccb6f5bb0367c8b8a6ed4529664b97812e58a","first_computed_at":"2026-05-18T04:12:33.598993Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:12:33.598993Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5j7nHMADonpYR79xykKGl3bKTG46bxIi+j+e5bWwq6yqCMAAL39YRlNLpc8TdzaId/m/hPh8cgZ2qEOxfANTCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:12:33.599518Z","signed_message":"canonical_sha256_bytes"},"source_id":"1106.1046","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:94771ae8fffb370ce1e3192bc2153cd8fdb874a6795dac3a168f1e5f2040581d","sha256:57a0d34b0613c82b76580afb62bb70b17804837bdfe5619c010efe0f6dc1392e"],"state_sha256":"f2bbc0668a5fc1c005e735798256812ee31fd21b3084183a34c7980a35ad0cc4"}
