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

ABSTRAKT

Convective heat transfer in laminar flow of transformer oil in a narrow channel (2 × 0.5 cross section) with vortex generators shaped as spherical dimples with a depth of 0.2 (in fractions of dimple spot diameter) placed at a heated wall surface is calculated using computational multiblock technologies for solution of the Navier−Stokes and energy equations within the framework of the generalized pressure correction procedure. Based on the comparison of channels with 15 and 121 dimples and a periodic module subject to periodic boundary conditions, vortex heat transfer enhancement is analyzed in comparison with a smooth channel without dimples and approximately fivefold heat transfer enhancement is validated.
