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

RESUMO

In this paper stability analysis of the ferrofluid layer heated from below when viscosity is temperature dependent is carried out analytically for the general nature of bounding surfaces. Using the analytical method of Pellew and Southwell [Proc. Roy. Soc. A, vol. 176, pp. 312–343, 1940] of conjugate eigenfunctions, the principle of exchange of stabilities (PES) is proved to be valid for the problem for very small values of magnetic parameter. This result yields that the ferroconvection is through the stationary mode only and the result is uniformly valid whether viscosity is temperature dependent or constant. However, for certain classes of hot fluids (in some astrophysical situations) the magnetic parameter can have large values, and this quantitative effect has a qualitative effect on the instability of ferrofluids. It is shown here that for large values of magnetic parameter oscillatory instability can exist and hence the bounds for the growth rate of unstable oscillatory modes of the problem are also derived herein.
