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

要約

Water/ethylene glycol (W/EG) mixture is a common heat transfer fluid in vehicle radiators that exhibits poor thermal performance. It can be substituted by nanocoolants (nanofluids as coolant) to enhance the overall heat transfer performance of radiators. However, addition of nanoparticles to enhance heat transport may be accompanied by a simultaneous increase in pumping power. In the present study, an experimental evaluation of thermohydraulic performance of graphite nanocoolant (W/EG-based graphite nanofluid as coolant) in vehicle radiators is carried out by utilizing an inhouse test rig. The thermal performance of the nanocoolant and the base fluid is compared at the same Reynolds numbers, coolant mass flow rates, and pumping power. The overall heat transfer coefficient is augmented with the use of a nanocoolant, while comparing with the same Reynolds number and coolant flow rate criteria. The enhancement is higher at lower air and coolant mass flow rates and gradually decreases as the flow rates increases. The same pumping power comparisons demonstrate that for low pumping power cases the overall heat transfer coefficient of the nanocoolant is higher than the base fluid, and the trend converses as the pumping power increases to higher values. The performance index, which indicates the net enhancement or diminution of thermal performance relative to the pumping power, is relatively more for graphite nanocoolant at lower coolant and air mass flow rates but diminishes in experiments with higher flow rates. This study shows that an analysis for finding the sweet spot is essential before applying graphite nanocoolant in vehicle radiators.
