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: 1.5 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: 1 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

要約

Natural convection in CuO-water nanofluid filled trapezoidal cavity having flexible side walls under the effect of inclined magnetic field was numerically investigated. The side walls of the trapezoidal cavity are adiabatic while top and bottom walls are at constant temperatures. The governing equations are solved with finite element method. The effects of the Rayleigh number (between 104 and 106), inclination angle of the side walls (between 10° and 60°), elastic modulus of the flexible side wall (between 500 and 105), Hartmann number (between 0 and 40), inclination angle of the magnetic field (between 0° and 90°) and solid volume fraction of the nanoparticle (between 0 and 0.04) on the fluid flow and heat transfer characteristics were studied. As the value of the Rayleigh number, inclination angle of the side wall and nanoparticle volume fraction increase, local and averaged heat transfer enhance. Local and averaged Nusselt number generally reduces with increasing values of Hartmann number. An optimum magnetic inclination angle is found to reach the maximum averaged heat transfer which depends on the inclination angle of the side wall. The influence of the elastic modulus of the flexible side wall on the heat transfer strongly depends on the inclination angle of the side wall.
