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

ABSTRAKT

This study uses the entransy dissipation extremum principle to optimize the geometry of conductive routes intruded into a cylindrical solid body for thermal cooling of a plastic bonded explosive. Conductive route cooling, which has relatively high thermal conductivity in terms of the heat-generating mediums into which it is introduced, presents itself as a viable passive method of reducing peak operating temperatures. The objective is to minimize the peak temperature caused by self-heating. Uniform internal heat generation is assumed for the solid body, which has adiabatic conditions on the outer surfaces and thermal contact with conductive routes. The total volume of the plastic bonded explosive and the volume of the conductive routes are fixed. The conductive routes are cylindrical with variable aspect ratios. The optimized geometry and performance are reported as functions of the ratio between the volume of the conductive routes and the plastic bonded explosive volume and the dimensionless parameter that accounts for the thermal conductive ratios. The main results indicate that for fixed conductive mass and thermal conductive ratios, there is an optimal radius-to-length ratio for the conductive routes.
