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

ABSTRAKT

We conducted a visualization measurement for isothermal turbulent water downward flow with rising droplets. Wobbling motion is observed for the droplets near the duct wall. The droplet wake flow with the asymmetric evolution of vortices modifies the near-wall turbulence: the lift-up of low-speed fluid is not observed clearly near the droplet. We also carried out a direct numerical simulation for non-isothermal turbulent downward flow in a vertical channel with an immiscible droplet whose density is lower than that of the flowing fluid and found that low-temperature fluid is pushed into the buffer region by the wallward flow along the cap of the droplet. The outward flow in the droplet wake causes the liftup of the hot fluid adjacent to the wall. These flows enhance the near-wall heat transfer.
