Four fluids were used to vary physical properties: pure distilled water, water with glycerol at 2 concentrations 1:1 and 1:2 v/v and water with Tween 20 at the concentration of 0.1g/l. The drop free fall height was varied to obtain a Weber number (We) between 10 and 2000. Results showed that obtained crater morphologies highly depend on the impacting drop kinetic energy E_{K}. Different behaviours during the drop spreading, receding and absorption are highlighted as function of the fluids viscosity and surface tensi","authors_text":"Elyes Nefzaoui, Olivier Skurtys","cross_cats":["cond-mat.soft","physics.geo-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2010-09-09T15:28:07Z","title":"Impact of a Liquid Drop on a Granular Medium: inertia, viscosity and surface tension effects on the drop deformation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1009.1806","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":"sha256:3db2a18c4b570d2d6e1cf6487144f55607d884efb9133a19c5d4b7b457aa35b4","target":"record","created_at":"2026-05-18T03:41:01Z","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":"0c204b59ffe6d8abd576d20a533437f3d817f492944f44c36569fe45b963e042","cross_cats_sorted":["cond-mat.soft","physics.geo-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2010-09-09T15:28:07Z","title_canon_sha256":"848ab2723e3baebf38375fbbce2c794d01b6f2bd2591b576f32f0ca33d37135f"},"schema_version":"1.0","source":{"id":"1009.1806","kind":"arxiv","version":1}},"canonical_sha256":"95b943085980da4511ace95f3767fca88963428839e081d3a4b56e4092e55471","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"95b943085980da4511ace95f3767fca88963428839e081d3a4b56e4092e55471","first_computed_at":"2026-05-18T03:41:01.590947Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:41:01.590947Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XhdFQAF0PHpAwqyAMZRlFaiZqocJ5Ec1uZA9yp6+4l74cs+uO7dzxkSdOvNv2wfe/30RLsoR1ZP4dmsx4evLBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:41:01.591548Z","signed_message":"canonical_sha256_bytes"},"source_id":"1009.1806","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3db2a18c4b570d2d6e1cf6487144f55607d884efb9133a19c5d4b7b457aa35b4","sha256:347828e049ab2c6362ec41c61595ffa0190eb299b3ca7b63c51f6a6e054dfba2"],"state_sha256":"52a16a0cf5d9da42d005610ce9a5cf1ea476f1062c1411aa9ddecf2bfdb86f3b"}
