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

Gas-centered swirl co-axial (GCSC) injectors are important to several propulsion applications. We report an experimental study of the near injector spray structure of a gas-centered swirl co-axial (GCSC) injector, where the effect of introducing swirl into the central gas stream has been investigated. Two different swirl numbers were chosen such that they span the critical swirl number for vortex breakdown of a swirling gas jet. Both co-swirl and counter-swirl conditions were investigated. A non-intrusive method based on feature correlation velocimetry (FCV) was used to quantitatively characterize the velocity of the liquid sheet as a function of gas phase Reynolds number (Reg), swirl number (S) and liquid phase Reynolds number (Rel). It was observed that as Rel increases or as Reg decreases, both spray cone angle and the intact sheet length at the injector exit appear to increase. In addition, swirl in the gas stream appears to cause a reduction in the mean liquid sheet thickness as well as the intact length irrespective of its direction. The effect of gas phase swirl is most pronounced at low Reg. An unsteady analysis of the flapping annular sheet reveals higher fluctuation frequency of the conical liquid sheet with a swirling central gas phase.
