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: 1.3 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: 1.7 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: 0.7 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: 0.00023 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: 0.244 SNIP: 0.521 CiteScore™:: 3.6 H-Index: 14

ABSTRACT

Two-dimensional double-diffusive convective flow in a duct is studied numerically. The duct is filled with electrically conducting nanofluid and subjected to mutually orthogonal static electric and magnetic fields. The one-phase Tiwari-Das model is employed to simulate nanoscale effects. The study is conducted for four different electroconductive nanofluids using water as a base fluid. The left and right plates of the enclosure are kept at different constant temperatures and concentrations. The top and bottom faces are insulated and impermeable to heat and mass transfer, respectively. The transport equations describe the velocity, temperature, and nanoparticle concentration fields. These coupled differential Navier-Stokes equations are nonlinear and therefore discretized via a robust finite difference method (FDM). The reduced difference equations are solved by incorporating the successive-over-relaxation (SOR) method. The results are shown graphically for various governing parameters. The skin friction, Nusselt and Sherwood numbers for the impact of selected electromagnetic, nanoscale, and thermophysical parameters are computed. The study is relevant to thermal power technologies, bioelectromagnetic therapy, and nuclear engineering heat transfer control.
