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

摘要

The objective of this study is to determine the possibility for decreasing the axial pressure gradients in the ignition cartridge of a 120-mm mortar propulsion system. The theoretical model and numerical code developed by the authors for ignition cartridge performance prediction as a part of a 3-D mortar interior ballistics (3DMIB) code was utilized in this study. Results show the presence of strong pressure waves in the current design of the ignition cartridge during the combustion processes in the granular bed. It was found that this pressure-wave phenomenon depends strongly upon the hierarchy and magnitudes of mass discharge rates of hot combustion products exiting through the 20 circular vent holes on the flash tube, which varied significantly along axial direction even though the vent-holes are distributed evenly. The highly non-uniform discharge of combustion products from the flash tube into the granular bed is believed to be the main reason for generating strong pressure waves in the existing M1020 ignition cartridge. The vent-hole pattern on the flash tube was systematically modified to achieve a more uniform discharge of igniter products into the granular bed. Numerical results showed that significant reduction in axial pressure gradients can be obtained by modifying the flash tube vent-hole sizes such that the igniter products are discharged more evenly at various axial locations in the granular bed. The reduction of the axial pressure gradient in the ignition cartridge can improve the reliability and reproducibility of the 120-mm mortar propulsion system.
