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

A simulation model has been developed in order to predict the behaviour of large solid motors during the ignition transient. The formulation of the model is finalized to obtain a numerical tool for the preliminary design phase. An accurate discretization in space and time is required to reproduce the sudden pressure rise during the motor start-up. Therefore, in order to limit the computational time, an unsteady quasi-lD Euler flow model has been adopted coupled with suitable semi-empirical models that take into account the main phenomena influencing the ignition transient. Special attention has been devoted to develop a reliable model to simulate the effect of the impingement of the igniter jets on the grain propellant surface (heating, ignition and combustion of the impingement region). The simulation model has been extensively tested and the numerical results have been compared with the experimental results obtained for largely different motor configurations.
