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 purpose of this paper is to analyze the effect of an atomizer design and liquid pressure on droplet diameter and a liquid spray atomization spectrum. Tests were carried out under constant laboratory conditions with the use of a GF 5405 atomizer with a diaphragm. With the use of the Malvern Spraytec laser diffraction method, the size of formed drops was analyzed. It was observed that with increased pressure, the typical diameters d0.1, d0.5, and d0.9 and Sauter mean diameter d32 get smaller. It is a logarithmic dependence. It was also proved that the size of drops depends on the distance between the diaphragm and the nozzle. Increasing the distance between the diaphragm and the outlet hole causes a considerable increase in the droplets diameters. A relative constant, the relative span RS for a given type of nozzle settings implies that atomizer operation is stable within the whole range of applied pressure values. The obtained data are very important in terms of atomizer design and agricultural treatments.
