摘要:	摘要： Polymer stretching in two-phase microfluidics is investigated by dissipative particle dynamics. The flow patterns can be controlled by wall wettability, flowrate ratio between two phases, and Reynolds number (Re). For neutral and partially wettable walls, segmented flows are formed and polymer stretching can be controlled by Re and segment length. At high Re, stratified flows are observed and the extension ratio can be tuned by the flowrate ratio. For nonwettable walls, slug flows are formed and polymer stretching can be controlled by Re and slug length. At high Re or flowrate ratio, annular flows are observed and high extension ratio can be easily attained. 其他題名： Biomicrofluidics 出版者： United States: American Institute of Physics 出版日期： 2012-06-01 出處： Biomicrofluidics, 2012-06, Vol.6 (2), p.24130 資源來源： AIP Journals (American Institute of Physics) 版權： American Institute of Physics 版權： Copyright © 2012 American Institute of Physics 2012 American Institute of Physics 識別號： ISSN: 1932-1058 識別號： EISSN: 1932-1058 識別號： DOI: 10.1063/1.4729129 識別號： PMID: 23762212 識別號： CODEN: BIOMGB
