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

The linear and nonlinear distortion and breakup of three-dimensional swirling or nonswirling annular and swirling conical thin inviscid liquid films are analyzed by means of a reduced-dimension approach. The films are unbounded in the downstream direction and discharge from an annular slit nozzle or atomizer into a gas of negligible density at negligible gravity conditions. Nonlinear numerical simulations describe the distortion of modulated, initially undisturbed films up to the time when film rupture first occurs. Linear and nonlinear solutions are presented and discussed for various configurations and with either dilational or sinuous three-dimensional modulations imposed on the films at the nozzle exit. Nonlinear growth rates can be significantly larger than those predicted by linear theory. Initially, axisymmetric disturbances remain axisymmetric and fluctuations in the circumferential direction generated by numerical error are not amplified for the considered cases. Overall, film topology at the time of film rupture suggests that single dilational or sinuous oblique waves will result in spiraling filaments detaching from the continuous film. Combination of clockwise and counterclockwise traveling dilational waves results in an approximately rectangular array of larger ligaments interspaced by thin fluid films indicating subsequent cellular-type breakup for both annular and conical configurations. Results for similar sinuous-mode modulations suggest film disintegration via shedding of continuous annular rings from swirling annular films and filament shedding from swirling conical films.
