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

With new pest control and bioregulating formulations under development and coming into use to improve spray retention and coverage, concerns have arisen about possible adverse effects on spray solutions due to fluid shear occurring in nozzles. Mathematical models were developed for velocity and shear-rate distributions for incompressible liquid flow through fan-pattern spray nozzles having approximately elliptic outlet orifices. The velocity distribution model was verified with phase/Doppler particle analyzer measurements and computational fluid dynamic simulations. A mean fluid velocity section of the model predicted the axial flow velocity to be 29.03 m/s for an 8002 brass fan-pattern nozzle with 276 kPa operating pressure, compared with a mean measured value of 29.85 m/s. With the shear rate model, it was found that use of an older equivalent-circle model resulted in significant underestimates of shear rates for fan-pattern nozzles. Liquid shear rates at the orifice wall varied with position, and were estimated to fall in the range 1.2 × 105 to 7 × 105 s−1 for the spray nozzles studied, depending on nozzle characteristics and operating pressure over a range of 138 to 414 kPa.
