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

Electro-acoustic characteristics of various acoustic oscillators operating on the basis of modulated electrical discharges are studied. The results of experimental studies of acoustic instability in model and real ram-jet and liquid-rocket combustors are presented in the form of the spectrum of the pressure-oscillation response to a harmonic perturbation generated by modulated discharges. A new promising method for active control of unstable combustion modes is developed based on the use of electrical discharges using a current- or voltage-stabilized power source. A selective sensitivity of the combustion zone to external perturbation is discovered in experiments with premixed hydrocarbon flames exposed to modulated discharges. Experiments performed in model combustors revealed that combustion instability arises when the fuel resonance coincides with the acoustic combustor resonance. The developed method and results are also applicable to propellant combustors and hybrid solid propellant chambers.
