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 article reports on an investigation of the influence of gas flow rate and liquid flow rate on the droplet sizes and velocities produced by a linear atomizer. Two-component phase doppler interferometry (PDI) is applied to a water spray to quantify the spray characteristics as a function of operating conditions. The point measurements are combined into a composite Sauter mean diameter (SMD) so that the data of droplet size experimentally determined by PDI can be compared with those calculated using an existing correlation. The present results demonstrate that: (1) droplet size decreases with an increase in atomizing gas pressure, i.e., the averaged SMD decreases from 82.3 μm to 51.3 μm when atomizing gas pressure increases from 1.378 × 105 Pa (20 psi) to 2.067 × 105 Pa (30 psi); (2) droplet velocity increases with atomizing gas pressure, i.e., the droplet velocity of 11- to 20-μm size range increases from 61.0 m/s to 80.0 m/s when the atomizing gas pressure increases from 1.378 × 105 Pa (20 psi) to 2.067 × 105 Pa (30 psi); and (3) the liquid height inside the crucible has little influence on liquid flow rate. Comparison of the measured SMD with the calculated SMD suggests that: (1) velocity of 11-to 20-μm droplets obtained by PDI may be used validly to estimate the atomizing gas velocity, and (2) the atomization efficiency has a significant influence on SMD and must be considered.
