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: 1.2 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

要約

The velocity, diameter, and flux of droplets in a rectangular wind tunnel simulating an engine port have been measured in and downstream of the region of impingement of an isooctane spray directed at 20° to the bottom flat surface, both at room temperature, with a vertical distance from the injector to the wall of 32 mm, an injection pressure of 3 bar, and a frequency of injection of 10 Hz. The cross-stream airflow velocities were 5 and 15 m/s and the injection periods 10 and 20 ms. The results show that the spray impinged on the surface, which became wet as the spray continued so that small-diameter droplets formed a cloud above the plate and immediately downstream of the location of impingement, with stronger convection of these small droplets with higher air velocity. The cloud was denser with a larger quantity of injected fluid and with lower air velocity. Also, the wall film survived from one injection to the next with lower air velocity and became thicker, so that splash atomization generated large droplets for some distance downstream and probably gave way to film stripping with slightly smaller droplets immediately above the film. Similar results, with larger concentrations of larger droplets, can be expected with smaller times between injections, and a hot surface will tend to evaporate the liquid so that the film will decrease in thickness, with reduction in secondary atomization.
