In such small scales, the complexity due to the coupling of fluid dynamics with the dynamics of ions is increased by the relevance of thermal fluctuations. Here, we present a mesoscale method based on the Dissipative Particle Dynamics (DPD) model of the fluid. Two scalar quantities, corresponding to the number of positive and negative ions carried by each DPD particle, are added to the standard DPD formulation. We introduced a general framework that, given the definition of the free-energy of the DPD particl","authors_text":"Alberto Gubbiotti, Carlo Massimo Casciola, Mauro Chinappi","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.flu-dyn","submitted_at":"2022-01-17T09:16:42Z","title":"EH-DPD: a Dissipative Particle Dynamics approach to Electro-Hydrodynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2201.06292","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":"sha256:9b842a6791ac38495133a3413bf487a329f2c2cd4a8a3062ea43604430e8f5d3","target":"record","created_at":"2026-07-05T03:48:56Z","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":"ccb5c714681488f8a60985848ae8a4e3752d4cad4dbafddb923065ca1f7e91ca","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.flu-dyn","submitted_at":"2022-01-17T09:16:42Z","title_canon_sha256":"6236004d39d7f2fd56956183bd5831d09a953d11ccc0bc29350f624894bfe362"},"schema_version":"1.0","source":{"id":"2201.06292","kind":"arxiv","version":1}},"canonical_sha256":"4f73b4d29c9bd1cb8940cc3e0a8871b151c51280f6d4ffada294f0acab794748","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4f73b4d29c9bd1cb8940cc3e0a8871b151c51280f6d4ffada294f0acab794748","first_computed_at":"2026-07-05T03:48:56.818845Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:48:56.818845Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wx0Z+3cKj+SWAvAQJeLtM3p1DKHIuhuB6h8hqiw3VOuvkHiTOtk/Hjb8mH6jbtl56q+PnrOSehqhLhJRgUGQBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T03:48:56.819244Z","signed_message":"canonical_sha256_bytes"},"source_id":"2201.06292","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9b842a6791ac38495133a3413bf487a329f2c2cd4a8a3062ea43604430e8f5d3","sha256:35e59342f38283c87d6cebfe60a7ad27b2babf8466ae6028e1a0adcddf698055"],"state_sha256":"769894644c85774bc96a22aef52403a2cf708ef6d7564e3dd6b4b341cb94e230"}
