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

A laser specklegram technique has been developed and applied to directly measure the wall temperature gradient for convective heat transfer problems. This relatively new technique has several advantages for heat convection measurements over conventional techniques, which usually require laborious corrections to account for the radiation and conduction heat losses. The specklegram technique provides extremely high resolution for the evaluation of local quantities, and full-field information can be obtained by photographically recording a single specklegram. Satisfactory measurement accuracy of the technique has been demonstrated when applied to a thermal layer along a vertical isothermal wall and a vertical channel flow between parallel isothermal channel. The technique has also been used to investigate a new problem: the dependence of heat transfer characteristics of converging channel flows on different inclination angles. The optimal exit opening ratio of the converging channel, (b/L)opt corresponding to maximum NuL is determined as 0.07, 0.1, 0.3, 0.35, and 0.4 for each of 0, 15, 30, 45 and 60° inclination angles measured from the vertical.
