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

ABSTRACT

A new spray computational fluid dynamics (CFD) model that comprises gas-jet and radius-of-influence collision, mean collision time, and interpolation method improvements was used to reduce grid-size, hole-location, and time-step dependencies in modeling group-hole-nozzle sprays. The spray model was validated against experimental results obtained from spray visualization and phase Doppler particle analyzer systems. The spray characteristics including spray penetration and droplet sizes of group-hole nozzles were also studied. Standard CFD spray models show significant dependencies of grid size, hole location, and time step for the calculated spray penetration of group-hole nozzles. On the other hand, the new spray model reduced the dependencies successfully for the present nonevaporating spray cases. The calculated results agreed well with the experimental results in terms of both spray penetration and SMD distributions. It was found that the sprays of the group-hole nozzle exhibit similar spray penetrations to those of a single-hole nozzle with the same overall hole area. The computations indicate that the group-hole nozzle has advantages in the near field for reducing spray droplet sizes.
