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: 0.7 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: 0.7 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: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

ABSTRACT

Slag formation and the accumulation found in aluminized solid propellant combustion occasionally cause the reduction of specific impulse and the rise of erosion rate at the nozzle and the insulation1−4 To improve reliability and performance of the solid rocket, the prediction of slag formation and the reduction of slag are very important requirements. To estimate the mechanism of the formation of Al2O3 slag, the information of Al droplet size distribution and combustion process in the flame are required as the first step. We observed the formation of the Al droplets at high pressure conditions with the CMOS (Complementary Metal Oxide Semiconductor) camera and the pockets of propellant cut with the microtome clearly. The diameters of the Al droplets in the flame near the propellant surface decreased with increasing pressure, and the sizes of the agglomerated Al droplets on the burning propellant surface were affected by pressure. The Al droplets in the pockets were smaller than that observed during the propellant combustion. We estimated that a diameter averaged Al droplet in the flame consisted of the Al droplets in 96 pockets at 1 MPa and the Al droplets in 50 pockets at 8 MPa.
