Moreover, we obtain error estimates with the aid of a relative entropy method. Our results hold provided that the mobility  mε>0  in the Allen-Cahn equation tends to zero in a subcritical way, i.e.,  mε=m0εβ  for some  β∈(0,2)  and  m0>0 . The proof proceeds by showing via a relative entropy argument that the solution to the Navier-Stokes/Allen-Cahn system remains close to the solution of a perturbed version of the two-phase flow problem, augmented by an extra mean curvature flow term  mεHΓt  in the interface motion. In a second step, it is easy to see that the solution to the perturbed problem is close to the original two-phase flow."}],"date_published":"2024-09-03T00:00:00Z","title":"Approximation of classical two-phase flows of viscous incompressible fluids by a Navier–Stokes/Allen–Cahn system","quality_controlled":"1","file_date_updated":"2024-09-09T08:43:32Z","article_number":"77","oa_version":"Published Version","year":"2024","isi":1,"author":[{"full_name":"Abels, Helmut","first_name":"Helmut","last_name":"Abels"},{"id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87","full_name":"Fischer, Julian L","first_name":"Julian L","orcid":"0000-0002-0479-558X","last_name":"Fischer"},{"id":"a60047a9-da77-11eb-85b4-c4dc385ebb8c","full_name":"Moser, Maximilian","first_name":"Maximilian","last_name":"Moser"}],"project":[{"_id":"0aa76401-070f-11eb-9043-b5bb049fa26d","grant_number":"948819","name":"Bridging Scales in Random Materials","call_identifier":"H2020"}],"volume":248,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","external_id":{"arxiv":["2311.02997"],"pmid":["39239088"],"isi":["001305530600001"]},"department":[{"_id":"JuFi"}],"month":"09","citation":{"short":"H.
