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

SINOPSIS

Experiments were conducted to investigate the heat transfer characteristics and cooling performance of subcooled liquid, water or methanol, flowing through rectangular cross-section microchanneled structures machined onto a stainless steel plate. The results provide significant data and considerable insight into the heat transfer and cooling mechanisms using microchanneled structures. It was found that a heat transfer or flow mode transition existed when the heating rate or wall temperature was increased. This transition was found to be induced by the variation in liquid thermophysical properties due to the great rise of the liquid temperature in the microstructures. The influence of such parameters as liquid velocity, subcooling, property variation, and microchannel geometric configuration on the heat transfer behavior were experimentally investigated, as well as the cooling performance, heat transfer and liquid flow mode transition. The experiments indicated that the single phase forced convection and flow boiling characteristics were different from those in normally sized tubes and the heat transfer in microchannels was intensified. No apparent partial nucleate boiling existed for subcooled flow boiling, i.e., fully-developed boiling was induced much earlier in the microchannels.
