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

RESUMO

Cavitation in atomizing orifices remains a consistent design problem in many modern engineering applications, and few analytical or numerical tools exist for its prediction. Visualization of cavitation in slot orifices at pressures up to 5 atm is reported. Slots with a minimum dimension ranging from 0.127 to 1.525 mm are studied. The incipient and desinent cavitation pressures are found for a variety of slot sizes. The extent of cavitation within the orifice as a function of cavitation number is also established for these slots. The liquid-vapor interface varies dramatically with slot geometry and local surface conditions at the inlet corner.
Cavitation in certain sized orifices is observed to experience a complex, and apparently cyclical, growth and disintegration process. This leads to the conclusion that the constant contraction coefficient assumed by previous works is in error. The growth cycle is examined and discussed for one such slot geometry.
