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

This article reports on a computational investigation of inductively charged sprays used in crop spraying. The charged sprays are produced using an air-atomizing induction-charging nozzle. In complementary research, the spray structures are experimentally characterized based on drop size and velocity data obtained using laser-based techniques, both in the free spray and in the near-target vicinity. The experimental deposition study used spectrophotometry analysis to quantify the drop residue on a grounded target. The study reported on here comprises the computational simulation of free spray and deposition aspects of charged and uncharged sprays, and uses the data obtained in the parallel investigation to determine the ability of the computational model to accurately predict such sprays. Experimental test results demonstrate the dominance of hydrodynamic effects within the charged free sprays, whereas, in the vicinity of a grounded target, the sprays are influenced by the attractive electrostatic force fields created, leading to greater drop depositions on the target than for an uncharged spray. These trends are confirmed by the computational results. However, there are differences of detail. The model generally underpredicts the effects of the electric fields on the spray motion near the target. This is probably due to an incorrect mass flux profile at the injector, leading to too little mass and, hence, charge being predicted in the target vicinity.
