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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

要約

Visualization and measurement of the spatial-temporal heat transfer characteristics of a turbulent water flow were conducted in a horizontal acrylic circular pipe, using a high-speed infrared thermograph (frame rate of up to 800 Hz). The inner diameter of the pipe was D = 20.4 mm and the Reynolds number varied from 1000 to 38,700. The test surface for the heat transfer measurement was fabricated from 22-µm-thick titanium foil coated with black paint, which was heated electrically with a constant heat flux. The heat transfer coefficient was evaluated quantitatively through heat conduction calculations for the heated surface considering the thermal inertia and diffusion. From the results of the present measurements, the convection pattern of high heat transfer spots was elucidated through frame-by-frame imaging of the instantaneous distribution. Also, the convection velocity was estimated from a 2D autocorrelation of the streamwise-temporal distribution. The convection velocity normalized by the mean velocity in the pipe was uc/um = 0.5−0.8 and that normalized by the friction velocity was uc+ = 10−14.
