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

The present work aims at studying the oscillatory motions of a rotating viscoelastic nanofluid layer contained between two free boundaries in natural convection. The Oldroyd-B model is utilized to describe the rheological behaviour of a viscoelastic fluid. The model used for nanofluid combines the effect of Brownian motion along with thermophoresis. Using linear stability analysis, the main focus is on the stationary and oscillatory convection for idealized boundary conditions. The explicit expressions of convective thresholds in terms of the control parameters of the system are obtained. The effects of the Deborah number, retardation parameter, concentration Rayleigh number, Prandtl number, Taylor number and Lewis number on the stability of the system have been investigated. Results indicate that there was competition among the processes of thermophoresis, Brownian diffusion, angular velocity and viscoelasticity which cause oscillatory rather than stationary convection to occur. Oscillatory instability is possible with both bottom- and top-heavy nanoparticle distributions. Regimes of stationary and oscillatory convection for various parameters have been derived numerically and discussed in detail.
