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

Nanofluids have promising characteristics of accomplishing high rate of heat removal from hot surfaces. An ultrafast cooling facility was developed at the School of Mechanical Engineering, KIIT University, Bhubaneswar, to investigate the effects of nanofluids impinging onto a heated steel surface of dimension 120 mm × 120 mm and having 4 mm thickness. K-type thermocouples were used for transient temperature measurement. Heat transfer experiments were conducted by using waterbased TiO2 nanofluids with four different particle concentrations (0.01 wt %, 0.03 wt %, 0.05 wt%, and 0.07 wt %) separately and compared with the performance of pure water. The addition of nanosized particles to the base fluid (water) could enhance the cooling process. The influence of nozzle tip to plate distance, mass concentrations, and fluid pressure upon the heat transfer rate was investigated. Detailed heat transfer characteristics in terms of time-dependent temperature distribution and surface cooling rate of the impingement flows with various combinations of mass concentration of nanoparticle were measured using a transient technique. The ultrafast cooling method based on nanofluids spray was found to be an efficient alternative cooling technique over the conventional water impingement cooling to achieve the optimal and high cooling rate. The overall improvement in cooling rate found to be 19.34%, 11.3%, and 7.14% using TiO2, Al2O3, and CuO nanofluids over the conventional liquid (water).
