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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

The convective stability of a horizontal, depthwise semi-infinite layer of liquid, with internal heat sources is investigated for the steady state, when the temperature distribution in the liquid is a function only of the vertical coordinate. The problem of stability is reduced to an eigenvalue problem for complex amplitudes of the perturbations, which is solved by the Bubnov-Galerkin method, combined with the method of collocations. The spectrum of decrements of small normal velocity and temperature perturbations is obtained, destabilization conditions are investigated. The dependence of critical Rayleigh and wave numbers on the governing parameters of the problem, associated with the strength of internal heat sources and the rate of evaporation from the free surface are obtained. The eigen-functions of the problem are determined.
