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

ABSTRAKT

An experimental investigation was carried out to study the natural convective air cooling of the printed-circuit-boards (PCBs) array which was set up vertically in a closed casing. The results show that there exists an unstable thermal boundary layer on the top wall, which brings about vortex flow and temperature oscillation in the casing. Because of the thermal instability the air circulation in the casing is unsteady. Time-varying recirculation presents in the PCBs array. Experimental results were correlated in the form of Nu = f(Ra, r) with Rayleigh-number ranging from 102 to 105 at Pr = 0.71.
