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

Краткое описание

The objective of this paper is to investigate the natural convection cooling of a heat source mounted inside a square cavity with special attention being paid to entropy generation. The cavity is filled with copper−water nanofluid; the right vertical wall is kept at a constant temperature, while other walls are adiabatic ones. The numerical scheme is based on the finite volume method with the SIMPLE algorithm for pressure−velocity coupling.

In this study, the influence of some effective parameters such as the Rayleigh number, location of the heat source, and solid concentration are studied; then, entropy generation due to the heat transfer irreversibility and fluid friction irreversibility as a function of Ra and solid concentration and heat source location is studied. The result shows that location of the heat source is an important parameter affecting the flow pattern and temperature field and variation of the entropy generation. Consequently the optimum case is selected since the thermal system could have the least entropy generation and the best heat transfer rate.
