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

RÉSUMÉ

The research reported in this article is an experimental investigation on the effects of nozzle specifications on spray and mixture properties of the group-hole nozzle by varying the included angle and interval between orifices. Since the group-hole nozzle spray loses its axisymmetry in the divergent angle and large interval cases, the original ultraviolet-visible laser absorption-scattering (LAS) imaging technique was first extended to simultaneous measurement of the total masses, as well as the mass distributions of vapor/liquid phases per projection area perpendicular to the laser beam in a nonaxisymmetric evaporating spray. Two major aspects of group-hole nozzle specifications have been investigated in this work. The results suggest that: (1) Increasing the divergent angle between orifices results in shorter spray tip penetration, larger spray cone angle, and significant increase in mass of fuel vapor, indicating the evaporation improvement. (2) In the case of group-hole nozzle with relatively large interval between orifices used in this study, the decreased penetration, larger spray cone angle, and reduced mass ratio of fuel vapor can be found. It is considered to be contributed to by the combined effect of direct droplets collision in the overlapping part of the two jets and the droplets collision and coalescence in the stagnation region inside the fuel spray.
