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

SINOPSIS

The present paper reports numerical results of natural convection and surface radiation within a square cavity filled with air and discretely heated and cooled from the four walls. In this study, the bottom active wall is at higher temperature than that of the top active wall. The remaining portions of the horizontal walls are considered adiabatic. The parameters governing the problem are the emissivity of the walls (0 ≤ ε ≤ 1), the relative lengths of the active elements (0.1 ≤ B = h'/H' = l'/L ≤ 0.9), and the Rayleigh number (104 ≤ Ra ≤ 3 × 106). The effect of these parameters on heat transfer and fluid flow within the cavity is examined. Results of the study are presented and compared to the case of pure natural convection for various typical combinations of the governing parameters in terms of flow and temperature patterns, average convective, radiative, and total Nusselt numbers. The heatlines visualization technique, which is a useful means for understanding the mechanism of heat flow, is employed to exhibit the direction and intensity of heat flux in the cavity.
