Differently from previous efforts, the LB equation for the fluid velocity is decomposed in a space of non-orthogonal central moments where the surface tension force is inserted directly in the equilibrium state. The present scheme is validated against well-consolidated benchmark tests, showing very good accuracy. Moreover, it outperforms the BGK approach in terms of stability, as our algorithm allows us to simulate a very large range of viscosity contrast.","authors_text":"Akiko Kaneko, Alessandro De Rosis, Shimpei Saito, Yutaka Abe","cross_cats":["physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2018-03-30T05:44:44Z","title":"Central-moments-based lattice Boltzmann scheme for coupled Cahn-Hilliard-Navier-Stokes equations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.11345","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:a2385c400b81d50abe0db4b3c57b3c7b1d47679de06060db8a42e10f2d2662a9","target":"record","created_at":"2026-05-18T00:19:43Z","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":"85d3715bea80c22266a7b99994595ef0a53f33a982b1f252f78569a0370bc62a","cross_cats_sorted":["physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2018-03-30T05:44:44Z","title_canon_sha256":"7a679cc7d1cfe0355f4851e2663fd7e60c30684f9916693b8357fa96dcc5f386"},"schema_version":"1.0","source":{"id":"1803.11345","kind":"arxiv","version":1}},"canonical_sha256":"1cd46847bc040ce2364a6a7b661fc2d0f7f6bfc623bee71c482a396e82487bd4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1cd46847bc040ce2364a6a7b661fc2d0f7f6bfc623bee71c482a396e82487bd4","first_computed_at":"2026-05-18T00:19:43.937435Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:19:43.937435Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"r7BG+xNcfKJmScKVNlrqtuSQNHaHUTU4Zu52iKac6gdVjGDyGQR372nFKyliSFhblOscD+Uab69SpyWPbG1jCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:19:43.938152Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.11345","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a2385c400b81d50abe0db4b3c57b3c7b1d47679de06060db8a42e10f2d2662a9","sha256:b2542fce76e9bd76266080e9334b94b562cdfd4b6931fb759de358ef01ab4765"],"state_sha256":"94493471e8803c3ca22e8c0243fe3acba038493f098d4f810e5b1ab70f346510"}
