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

RÉSUMÉ

The flat horizontal layer of the poorly conducting fluid is placed in the alternating electric field and heated from above. Its behavior is investigated in the electroconvection low-mode model. The approximation in which density and conductivity of the fluid are linearly dependent on temperature is used. Linear instability is analyzed by means of the Floquet theory. The system of eight differential equations, which describe the motion of the fluid, is integrated using the Runge-Kutta-Merson fourth-order method. The marginal stability curves are plotted in coordinates "wave number -nondimensional electric parameter". The critical values of the wave number and the nondimensional electric parameter are determined for various external influence frequencies. The nonlinear regimes of the fluid flow are investigated at the critical value of the wave number. The fluid electroconvection flow intensity as a function of the nondimensional electric parameter is plotted. The various types of the oscillation regimes are discovered, and the competition regions of different electroconvection modes with various flow intensities are found.
