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

RESUMO

The effects of primer configuration in the propellant chamber of the gun system utilizing granular solid propellant on the ignition performance (such as the formation of differential pressure between the breech pressure and the projectile base pressure) are numerically investigated. Simulations of experiments varying the primer length, the total area of flash holes and the igniter mass are carried out using the solid/gas two-phase fluid dynamics code for two-dimensional axisymmetric calculation of Eulerian gas flow and discrete solid propellant particles. The code simulates the igniter combustion in the primer, the movement of burning solid propellant grains, and the formation of pressure gradients in the chamber in the ignition process. The negative differential pressures between the breech and the rupture disk measured in the experiment are well predicted by the simulations for various primer conditions. In the process of igniting the solid propellant, the propellant grains are accelerated toward the rupture disk by the igniter gas flows from the primer and pressure gradients. From the simulated results, it is shown that the differential pressure is caused by the movement of solid propellant grains in the chamber depending on the primer conditions.
