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: 1.2 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: 1.8 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

ABSTRACT

Dynamics of the emulsified fuel explosive dispersal is investigated. Equations of a fuel shell radial motion prior to the fragmentation are derived and studied. It is shown that the shell is affected by huge inertia forces, caused by the acceleration of 109 m/sec2 order, when 1g of fuel is affected by the inertia force of 106 N/g. This allows formulating hypothesis regarding micro-explosion mechanism, which implies the fuel shell perforation by water vapor due to Rayleigh−Taylor instability. Verification is carried out via analysis of the necessary conditions of instability at both shell surfaces. Fuel shell dynamics is studied numerically being based on the derived differential equation of motion. It is concluded that the instability performance has high feasibility at external shell surface close to the moment of the utmost expansion. Shell bursting is then modeled being based on analogy of the shell dynamics and "claviform" mode of a drop breakup. Formulae for a number and sizes of secondary droplets left by the micro-explosion are obtained. They show that the micro-explosion increases the liquid fuel surface and evaporation rates by 2 orders. Acoustic field of the totality of the spray volume micro-explosions is strong enough to affect the rates of the component mixing and chemical reactions in a jet spray.
