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

ABSTRACT

In this paper the linear stability of two liquid layers with flat free-surface coating of both sides of a wall of finite thickness and thermal conductivity is investigated under the assumption that the liquid/gas Biot numbers are very small. It is supposed that gravity is negligible and that the atmospheres at both sides of the system have different temperatures. These conditions allow for the formation of very large thermocapillary convection cells. Thus, the small wave-number approximation is done up to fourth order to calculate the marginal Marangoni number. From this result, the critical Marangoni number (Mac) and its corresponding wave number (kc) have been calculated numerically. The wave number corresponding to the maximum growth rate (kmax) is also calculated for a Marangoni number slightly above criticality. It is shown that, under these conditions, the flow is stationary. It is found that Mac may have two magnitudes, one positive and another one negative, depending on the magnitude of some particular parameters of the problem. It is shown that kc may be zero or different from zero with small but finite magnitude. Some parameters are fixed and the numerical results are presented by means of plots of Mac, kc, and kmax against different important parameters of the problem.
