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: 0.5 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: 0.8 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: 0.2 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: 0.00018 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: 0.11 SJR: 0.286 SNIP: 1.032 CiteScore™:: 1.6 H-Index: 10

SINOPSIS

In this paper the nonlinear stability of viscoelastic thin films falling down a smoothly deformed wall is investigated. The viscoelastic fluid satisfies the Oldroyd's nonlinear constitutive equation. Viscoelasticity adds new degrees of freedom to the fluid motion and it has been shown that the flow becomes more unstable than that of a Newtonian fluid. Here, it is shown that it is still possible to stabilize the viscoelastic thin film in a passive way by means of a spatial resonant effect due to the waviness of the wall, as done before for a Newtonian fluid in the small wave-number approximation.
