A finite volume scheme is used on a structured Cartesian grid to solve the Euler equations, and the bubbles are discretized by a diffuse interface method. We investigate the propagation of the collapse wave front through the cloud and provide comparisons to simplified models. We analyze the flow field to identify each bubble of the cloud and its associated microjet. We find that the oscillation frequency of the bubbles and the velocity magnitude of the microjets depe","authors_text":"Fabian Wermelinger, Jonas \\v{S}ukys, Petr Karnakov, Petros Koumoutsakos, Ursula Rasthofer","cross_cats":["physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-04-30T08:32:33Z","title":"A Computational Study of the Collapse of a Cloud with 12500 Gas Bubbles in a Liquid"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.11079","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:e26bad53fdae1a5d1c1a9cd465f902f7d3a51021b516ab1bc10b75b61f4e22a9","target":"record","created_at":"2026-05-17T23:43:38Z","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":"77a186d051024394cec02d8ac7b0686d3d3f0e5f876461c1f119e2859e0e7a3f","cross_cats_sorted":["physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-04-30T08:32:33Z","title_canon_sha256":"d3bb1ff98bf0b62169c09a8501e8edd36edd53d9fffc198a06f933e9fb9cb30d"},"schema_version":"1.0","source":{"id":"1804.11079","kind":"arxiv","version":1}},"canonical_sha256":"0f57040a346de38b500ada1137e06777b33b9188cff778d153d305d6e0904c10","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0f57040a346de38b500ada1137e06777b33b9188cff778d153d305d6e0904c10","first_computed_at":"2026-05-17T23:43:38.383331Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:43:38.383331Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZmxoItY8G+VSEeYmmxC+pM454vSr8m0q+s1sLblhdnWrDcIDrZg37dDIRu0eUX3AoK4RF1R08ijz4Ut2vNUUAw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:43:38.384203Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.11079","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e26bad53fdae1a5d1c1a9cd465f902f7d3a51021b516ab1bc10b75b61f4e22a9","sha256:893a04cbff98a8052474762ed8db1dd524ec6f4a7c0ced7fe7d3101116dbc3c0"],"state_sha256":"51163e125ab42386bb307faa07a04d8b3d3d22ae775593f24054221a204f231a"}
