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: 2.3 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: 1.8 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: 0.2 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

Краткое описание

The influence of coatings on thermal characteristics of the fins having various shape (longitudinal and circular fins, cylindrical pins) has been investigated. Heat transfer in the simplified and two-dimensional statements of the problem is considered and analytical solutions for the temperature distributions and thermal efficiency of the fins with coatings are obtained. The simplified and two-dimensional solutions for the composite fins are compared and the errors that can appear in a simplified heat transfer model are obtained. The contribution of the top surface to the total heat flux from a composite fin is determined. The condition of the "advantage" for a composite fin is found. The optimum sizes of the longitudinal fins with uniform and nonuniform coatings are determined. It is shown that the optimum sizes of the fins with polluting or protective coating depend on the Biot number of the coating and can considerably differ from the optimum sizes of "clean" fins. The influence of nonuniform pollution on thermal efficiency and optimum sizes of the longitudinal fins is studied. The correction factors for fin efficiency and optimum fin sizes which take into account the nonuniformity of pollution have been calculated.
