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: 1.7 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: 1.4 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: 0.6 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

要約

Steady natural convective flow and heat transfer in a two-dimensional enclosure with a centrally placed isoflux thin partition utilizing different fluids are investigated for a range of Rayleigh numbers, partition heights, and aspect ratios. The enclosure has two vertical isothermal walls and two horizontal adiabatic walls. The present study is based on a similar configuration with an isoflux thin partition symmetrically embedded at the bottom wall. The governing equations are modeled by a stream function-vorticity formulation and are solved numerically by the finite-difference approach. The Rayleigh number ranges from 103 to 106 . The study includes computations for enclosures at various partition heights ranging from 0.2 to 0.7, aspect ratio from 0.5 to 2, and isoflux values ranging from 0.5 to 2. The fluids used are air, fluorocarbon liquid (FC 77), and ethylene glycol. A comprehensive comparison with previously published numerical and experimental results showed an excellent agreement. The results are presented for different fluids in the form of streamlines and isotherm plots. Variation of the local Nusselt number over the isoflux partition and isothermal wall provides a valuable insight into the physical processes. A numerical correlation is proposed for the heat and fluid flow studies in a wide range of thermal and geometric parameters.
