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

SINOPSIS

Natural convective heat transfer of copper--water nanofluids in a square enclosure with sinusodally alternating temperature at one vertical wall, relatively low temperature at the opposite sidewall, and adiabatic at the other walls is investigated. The transport equations are solved numerically by finite volume approach using the SIMPLEC algorithm. Calculations are performed for the Rayleigh number from 104 to 106, nanoparticle volume fractions from 0 to 0.2, dimensionless amplitude from 0 to 1.0, and dimensionless frequency from 0.1 to 200. The fluctuating behaviors are found for the flow fields and temperature fields as a result of the alternating temperature. The utilization of nanoparticles enhances heat transfer especially at high Rayleigh numbers, and the percentage increase in the time-averaged Nusselt number is 37.61%, when the solid volume fraction is increased from 0 to 0.2. In addition, the alternating temperature amplitude and frequency affect heat transfer of nanofluids. When the dimensionless amplitude is increased from 0 to 1, the percentage increase in the time-averaged Nusselt number is 12.24%. The double-humped resonance phenomenon of nanofluids heat transfer is observed for variation of the temperature oscillation frequency.
