The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

ABSTRACT

A linear analysis method has been used to investigate the two-dimensional temporal instability behavior of viscoelastic liquid sheets of the parabolic velocity profile moving through the viscous ambient gas. The velocity profile of the liquid sheet and the gas boundary layer thickness were taken into account. It is seen that the velocity gradient of the viscoelastic liquid sheets is greater than that of the corresponding Newtonian ones. Moreover, the effects of the time constant, the elasticity number, and the liquid and gas Reynolds number on the velocity profile of the viscoelastic liquid sheets are researched. The relationship between growth rate and wave number of the disturbance wave was obtained with linear stability analysis and solved with a spectral method. The rheological parameters and flow parameters have been tested for their influences on the instability of the viscoelastic liquid sheets. The result reveals that the disturbances grow faster on the viscoelastic liquid sheets than on the Newtonian ones with the identical zero shear viscosity. Furthermore, the time constant, the liquid and gas Reynolds number, the Weber number, and the elasticity number have a great influence on the temporal stability of the viscoelastic liquid sheet.
