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

Краткое описание

A simple method, which had been proposed by the authors to compute grain burnback during the operation of a solid-propellant rocket motor, is revisited. The method uses a fixed grid, which is imposed on the propellant grain. The intersection of the moving solid-gas interface with the grid is tracked and the burning surface is described using straight lines to compute the burning surface area and the port area. The revised version allows a more accurate tracking of the propellant regression than in the original method. The precision of the procedure is greatly increased by recording both the position and inclination of the solid-gas interface with respect to the grid lines, and the grain geometry is described using straight lines and circular arcs. Coarser grids can be used for the same expected error and the corresponding computing time is reduced. Improvements include the capability of handling surface merging and spatially dependent burning rates.
