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

SINOPSIS

One method for generating pulsed, supersonic liquid jets is by projectile impact, often referred to as the "Bowden-Brunton" method. In this article, the fundamental processes by which such jets are generated are investigated. The momentum transfer from the projectile to the liquid and the shock wave reflection within the nozzle cavity are the key items of interest. In this study, a new one-dimensional analysis has been used in order to simplify this complex and difficult problem. First, the impact pressure obtained from the projectile is derived. Then, an investigation of the intermittent pressure increase in both a closed end cavity and a simple stepped, cross-sectional nozzle cavity (sac) is carried out. The nozzle pressure and final jet velocity are estimated and compared with experimental results, with which they show good agreement, and to a previous analytical method. Also, experimental shadowgraph visualization of the jet penetrating the air is presented. Some interesting characteristics, such as a rippled leading edge main (bow) shock wave in the air and the appearance of a second shock wave, can be seen. These characteristics relate well to those anticipated by the analysis.
