The two fluids are assumed to be immiscible, meaning that they are separated by an interface. With respect to the motion of the interface, we consider pure transport by the fluid flow. Along the boundary of the domain, a complete slip boundary condition for the fluid velocities and a constant ninety degree contact angle condition for the interface are assumed. In the present work, we devise for the resulting evolution problem a suitable weak solution concept based on the framework of varifolds and establish as the main result a weak-strong uniqueness principle in 2D. The proof is based on a relative entropy argument and requires a non-trivial further development of ideas from the recent work of Fischer and the first author (Arch. Ration. Mech. Anal. 236, 2020) to incorporate the contact angle condition. To focus on the effects of the necessarily singular geometry of the evolving fluid domains, we work for simplicity in the regime of same viscosities for the two fluids.","lang":"eng"}],"publication":"Journal of Mathematical Fluid Mechanics","volume":24,"license":"https://creativecommons.org/licenses/by/4.0/","has_accepted_license":"1","status":"public","oa_version":"Published Version","_id":"11842","external_id":{"arxiv":["2112.11154"],"isi":["000834834300001"]},"date_published":"2022-08-01T00:00:00Z","file_date_updated":"2022-08-16T06:55:22Z","related_material":{"record":[{"id":"14587","relation":"dissertation_contains","status":"public"}]},"article_type":"original","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"quality_controlled":"1","project":[{"_id":"0aa76401-070f-11eb-9043-b5bb049fa26d","call_identifier":"H2020","name":"Bridging Scales in Random Materials","grant_number":"948819"}],"oa":1,"publisher":"Springer Nature","date_updated":"2024-03-22T13:21:27Z","department":[{"_id":"JuFi"}],"publication_status":"published","ec_funded":1,"article_processing_charge":"No","article_number":"93","type":"journal_article","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"year":"2022"}
