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

摘要

This study examines pressure drop during condensation of R-245fa pure vapor inside two separate horizontal coaxial double-pipe test sections with coiled-wire inserts assembled in series. For each inserted tube and the plain tube, data were collected for mass fluxes in the range of 100 to 250 kg/m2s in increments of 50 kg/m2s for vapor qualities ranging from 0.1 to 0.9. It was observed that the pressure drop inside a horizontal tube is a complex function of vapor quality, mass velocity, and coil pitch, and in a low vapor quality region. The highest pressure drop ratio was 13.33 for a coil pitch of 3.0 mm at a refrigerant mass flux of 150 kg/m2s.
