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

Mean drop size data are presented for single-phase Newtonian fluids of varying viscosity sprayed using a two-dimensional research nozzle. The effect of liquid viscosity on mean drop size is observed to be nearly constant over the range of the test matrix, with Sauter mean diameter (SMD) proportional to μ0.2. As expected, SMD is observed to increase with liquid discharge slot width, tL but only at conditions of high viscosity and low aerodynamic shear. As fluid viscosity is reduced or aerodynamic shear is increased, the dependence on liquid film thickness becomes negligibly small. No effect of air discharge slot width was observed for the range of conditions employed in this study. The data also indicate that an increase in relative velocity, VR, results in a decrease in spray mean drop size, with the degree of reduction being dependent on the viscosity of the fluid being sprayed. Finally, the influence of air-liquid ratio (ALR) on atomization was constant over the entire test matrix, varying with the square root of (1 + 1/ALR), This dependence was noted by Jasuja [3] when spraying liquids whose viscosities were much lower than those reported here. The data were analyzed using a control-volume approach and an expression provided that relates mean drop size to ALR, VR, tL the liquid density, and surface tension, plus a parameter termed e that describes the fraction of atomizing air that contributes all of its energy to increasing the surface energy of the droplets.
