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

SINOPSIS

Recent developments in the formulation of a multidimensional, multiphase interior ballistics model for solid propellant chemical propulsion used for gun charges are discussed in relation to ignition phenomena. The computational fluid dynamics model simulates primer function, propellant ignition, flamespreading, charge compression, and pressure wave generation and has been under development and validation for a number of years. During that time, the model has been successfully applied to a wide range of gun calibers. This paper discusses recent model extensions that enable the examination of the physical principles associated with bayonet or piccolo-type primers and igniters for medium and large caliber guns as well as tailboom-type igniters for mortars. The model is shown to be useful in determining the compatibility of piccolo primer configuration and energetic fill with the chemical properties of the main charge propellant in medium caliber guns. In some cases, less prompt ignition and chamber pressurization results when the chemical properties of the main propellant are altered and no change is made to the characteristics of the primer. In addition, the model can aid in determining the cause of apparent non-sequential ignition of propulsion increments in mortars and in linking such behavior to the dynamics of primer function within the mortar tailboom.
