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

The development of phase-Doppler anemometry has provided a reliable measuring technique for studying local particle size and particle velocity distributions in sprays. Using this technique, the present article summarizes viscosity and surface tension effects on the properties of liquid sprays produced by pressure swirl atomizers. Mean droplet sizes and mean velocities were computed from the measured joint size/velocity distributions to discuss the spray properties in the terminology largely employed in the field of liquid sprays.
The results indicate an increase of the mean diameter with increasing surface tension and increasing viscosity. Concerning the shape of the size distributions, the results suggest that narrow size distributions can be generated by low-viscosity and low-surface-tension fluids. Also, it is shown that surfactants do not lead to an effective surface tension reduction in atomization. Moreover, they introduce a non-Newtonian behavior, which results in a decrease of the number of droplets in the small size range.
