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

ABSTRAKT

This study concerns visualization of pulsed sprays of a gasoline port fuel injector under ambient conditions. One-, two-, and four-hole configurations all with the same hole diameter are compared. The investigations on the two-hole configuration include adjacent and diagonal holes. The instantaneous penetration length, the jet breakup length, cone angle, and the droplet diameter distributions are evaluated along the spray axis at different injection pressures. As the spray penetration evolves, the liquid jet breaks up some time later, and reaches a nearly constant breakup length throughout the subsequent development of the spray. Unlike the single-hole spray, the two-hole spray exhibits a mild increase in the breakup length with increase in the injection pressure. The breakup length with the diagonal two-hole configuration is much shorter than with the adjacent one. The diagonal two-hole configuration exhibits a high cone angle relative to two-hole and four-hole cases. In all the cases, the mean droplet size decreases with injection pressure and remains nearly constant in time at any axial location. While the single-hole and adjacent two-hole injectors indicate coalescence of droplets, the diagonal two-hole case shows a decrease in the Sauter mean diameter of the droplets with axial distance. The four-hole injector produces nearly constant droplet size. The shorter breakup length, higher spread, and smaller droplet sizes in the two-hole diagonal configuration support an enhanced entrainment of ambient air as compared to the two-hole adjacent and four-hole injector configurations.
