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

Aluminum particles of different shapes have broad applications as a solid fuel ingredient in propellants and explosives. The objective of this paper is to develop a comprehensive model of aluminum particle ignition and combustion processes. A new model of aluminum droplet combustion was formulated using the volume of fluid (VOF) multiphase approach. The VOF approach can naturally handle phase interactions such as surface tension, evaporation, heterogeneous reactions, oxide condensation, and oxide recession. Similar to experimentally observed phenomena in a parallel study, calculated results demonstrated the importance of particle spin rates on the morphology of the molten Al flake. At high spin rates, a disk shaped aluminum flake can break apart into multiple fragments as found in recovered samples. This phenomenon is important in the combustion of energetic particles since the exposed surface area can change by the dynamic interaction between the surrounding fluid with the particle. Numerical results obtained from this generalized multiphase combustion model have also demonstrated the flame development around the Al particle. The time evolution of molten aluminium particles into various shapes was also demonstrated as a strong function of their initial geometric configurations.
