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

It is necessary to understand the characteristics of the circulating air flow inside the household refrigerator in order to reduce energy consumption and find the optimal chilled air distribution within it. To investigate the air flow precisely, particle image velocimetry (PIV) was used to visualize the flow field, and a computational simulation was also conducted. For the visualization experiment, the airflow issuing from two major entrance ports in the frozen food compartment model (made of transparent acrylic resin plate) was visualized by a Nd:YAG pulsed laser light sheet, and a number of flow images were processed by the grey level difference method. A study to obtain turbulence statistics was also performed, and results of the mean velocity field were compared with the computational results. For the computational simulation, a 3D-CAD modeler (UniGraphics) was used to generate a full geometry of the frozen food compartment and the grid generation, and simulations were carried out by a commercial fluid dynamics program, FLUENT, with an RNG k−ε turbulence model. The results of the two approaches showed similar flow fields and revealed that the secondary flow, developed from the initial region of the entrance ports, may play an important role in the real (chilled) flow distribution.
