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

A binary liquid mixture which consists of a low-vapor-pressure liquid and a propellant has been considered. When the mixture is discharged through an appropriate injection system, the propellant undergoes a rapid flash boiling process which results in a disintegration of the continuous liquid phase into small droplets. In the present work, the effect of the injection system design on the spray characteristics is investigated experimentally. It is concluded that: (1) the real behavior of the solution, as compared to ideal solution behavior, is an important factor; (2) the important stage of nucleation occurs at the metering orifice and apparently, the main duct does not play any significant role in the bubbles' nucleation; (3) neither the expansion chamber diameter nor its length has any significant effect on the droplet Sauter mean diameter (SMD), (4) an orifice's diameters ratio (metering to discharge) between 0.6 and 0.9 results in a minimum SMD; and (5) the SMD is correlated well with a modified version of the Jakob number of the form of Ja* = xβ(CpΔT/hfg).
