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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

要約

It is well known that significant numbers of investigations have studied impinging circular jets; relatively fewer studies have dealt with annular jets. In this work, numerical investigations predict the transport phenomena and Nusselt number distribution of laminar-turbulent annular jets on a surface due to impingement. For analysis purposes, the annular jet characteristics are compared with a circular jet at the nozzle exit with the same Reynolds number and the same amount of mass and momentum efflux. The Reynolds number is defined on the basis of the width of the annular part of the jet. It was found that heat transfer from the annular jet was 20%–30% less than for the circular jet. The peak heat transfer zone is observed downstream of the annular ring. This location moves downstream as the Reynolds number increases. The skin friction pattern shows a similar trend. The nature of distribution of the Nusselt number over the impinging surface scales with Re0.54 for the laminar region and with Re0.66 for the turbulent region.
