We consider the case that the fluid densities may contain a vacuum, and the viscosities are density-dependent functions. Under suitable assumptions on the initial data, we show that the finite-energy (i.e., in the inhomogeneous Sobolev space) classical solutions to the Cauchy problem of this coupled system do not exist for any small time.", "revisions": [ { "version": "v1", "updated": "2024-02-04T15:25:53.000Z" } ], "analyses": { "subjects": [ "35A01", "76N06", "35Q31" ], "keywords": [ "classical solutions", "non-existence", "isentropic compressible navier-stokes equations", "small time", "two-phase flow model consisting" ], "tags": [ "journal article" ], "publication": { "publisher": "IOP" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
