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

ABSTRAKT

In this paper the mechanisms of a temporal electrohydrodynamic axisymmetric instability of non-Newtonian dielectric liquid jets moving through a dielectric gas with surface tension gradient have been investigated. The dispersion relation between the nondimensional growth rate and the nondimensional wave number for the eight-constant Oldroyd model is derived using appropriate boundary conditions. The effects of different parameters such as Ohnesorge number, Weber number, elasticity number, deformation retardation to stress relaxation ratio, gas to liquid density ratio, gas to liquid velocity ratio, electric field, and the dielectric constants of the two media on the stability behavior of the system are discussed in detail. Comparisons between the cases of absence or presence of electric field, non-Newtonian fluids, surface tension gradient, and gas to liquid velocity are achieved. The present work is a good foundation for the invistigations of the instability and breakup of non-Newtonian liquid jets with electric field effect and surface tension gradient existence.
