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

Gelled propellants are of interest for rocket and ramjet propulsion systems because of their safety and performance benefits. During spray tests with doublets, such as on impinging jet injectors, it was observed that the breakup of the fluid sheet of several gels did not lead to the formation of droplets; instead, threadlike structures were formed. Such structures may cause a reduction in combustion efficiency and the accumulation of unburned material in the combustion chamber. The goal of the work presented here is to determine which physical properties influence thread formation. Spray tests were conducted with Boger fluids under atmospheric conditions concerning pressure and temperature with a like-on-like impinging jet injector. The range of injection velocities from 5 to over 70 m/s was studied. Images of the sprays were obtained with a shadowgraph technique. In order to obtain quantitative results from shadowgraph images, a code was implemented to determine a characteristic dimension of the threads. A clear correlation between the relaxation time, which is an indicator of the intensity of elastic effects, and the dimension of the obtained threads was observed. These results suggest that thread formation is caused by nonlinear elastic effects, while shear viscosity and surface tension do not seem to influence the formation of these structures.
