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

ABSTRACT

Natural convection in a closed square cavity induced by two mutually orthogonal heat-generating baffles is considered. A numerical investigation is made to understand the effect of baffle dimensions on the resulting heat transfer characteristics. The coupled nonlinear governing equations were solved by the finite difference method using the Alternating Direction Implicit technique and the Successive Over-Relaxation method. The results obtained indicate that the flow and temperature fields strongly depend on the dimensions of heat-generating baffles. It is found that when both baffles are mounted inside the cavity an increase in the length of any of the baffle results in a proportionate increase in the overall heat transfer rate. But no significant changes in the overall heat transfer rate occur for different positions of the baffles. When the vertical baffles is mounted on the cavity wall it extracts heat energy from the cavity and behaves like a cold wall for an increase in its length. The study provides additional basic design information during fabrication in microelectronics industry.
