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

An experimental investigation was conducted to explore the effects of equivalence ratio and air mass flux on the combustion efficiency and particle size distributions in a solid fuel ramjet using a fuel grain highly loaded with boron carbide. Particle distributions were measured at the grain exit and at the nozzle entrance using a Malvern 2600 USD and at the nozzle throat using a collection probe. Combustion efficiency increased with increasing equivalence ratio (grain length) and decreasing air mass flux. In general, the particle distribution was trimodal or quadrimodal with mode peaks at approximately 4, 15, and 25 μm and possibly one at less than 2 μm. Probe measurements at the nozzle throat showed that considerable mass was contained in spherical particles smaller than 0.5 μm—outside the measurement range of the Malvern The larger particles were the result of surface agglomeration, primarily within the recirculation region. Short grains that consisted primarily of the recirculation region produced larger particles and lower combustion efficiencies. Higher inlet air temperatures produced higher combustion efficiencies, apparently the result of enhanced combustion of the larger boron carbide particles that burn in a diffusion controlled regime.
