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 pressure swirl atomizer is widely used in liquid fuel combustion devices in the aerospace and power generation industries. The experimental and numerical predictions of air core diameter da, the coefficient of discharge Cd, and the spray cone angle ψ of a cylindrical swirl-spray pressure atomizer have been made in the present study. The standard k-ε model of turbulence is used for numerical computation of flow within the nozzle. The diameter of the stable central air core inside the nozzle has been predicted at given operating conditions. The values of Cd and ψ have been evaluated from the radial distribution of velocity components of liquid flow at the nozzle exit plane. It has been observed from numerical and experimental investigations that the coefficient of discharge Cd decreases, while the air core diameter da and the spray cone angle ψ increase with the increase in nozzle flow in its lower range. However, all these parameters, Cd, ψ, and da, finally become independent of nozzle flow. Both da/D and ψ increase but Cd decreases with a decrease in Dp/D for the nozzles of constant L/D, where Dp, D, and L are the entry port diameter, swirl chamber diameter, and length of atomizer, respectively. Also, both da/D and ψ decrease, while Cd increases with an increase in L/D for the nozzles of constant Dp/D.
