--- res: bibo_abstract: - 'We report a direct-numerical-simulation study of the Taylor-Couette flow in the quasi-Keplerian regime at shear Reynolds numbers up to (105). Quasi-Keplerian rotating flow has been investigated for decades as a simplified model system to study the origin of turbulence in accretion disks that is not fully understood. The flow in this study is axially periodic and thus the experimental end-wall effects on the stability of the flow are avoided. Using optimal linear perturbations as initial conditions, our simulations find no sustained turbulence: the strong initial perturbations distort the velocity profile and trigger turbulence that eventually decays.@eng' bibo_authorlist: - foaf_Person: foaf_givenName: Liang foaf_name: Shi, Liang foaf_surname: Shi - foaf_Person: foaf_givenName: Björn foaf_name: Hof, Björn foaf_surname: Hof foaf_workInfoHomepage: http://www.librecat.org/personId=3A374330-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0003-2057-2754 - foaf_Person: foaf_givenName: Markus foaf_name: Rampp, Markus foaf_surname: Rampp - foaf_Person: foaf_givenName: Marc foaf_name: Avila, Marc foaf_surname: Avila bibo_doi: 10.1063/1.4981525 bibo_issue: '4' bibo_volume: 29 dct_date: 2017^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/10706631 dct_language: eng dct_publisher: American Institute of Physics@ dct_title: Hydrodynamic turbulence in quasi Keplerian rotating flows@ ...
