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

Multi-cycle experiments on a multi-tube pulse detonation engine (PDE) were carried out. The PDE consisted of four detonation tubes. They were ignited sequentially with the operation frequency of 120−200 Hz (30−50 Hz/tube). The exhaust gas flows from the detonation tubes were combined in a cone-shaped collecting duct, to the exit of which a straight exhaust duct was connected. In order to investigate the controllability of pressure pulses in the PDE system, an orifice was installed at the exit of the straight exhaust duct. In the experiments, the size of the orifice, the length of the straight exhaust duct, and the operation frequency were varied, and pressure histories at the exit of the straight exhaust duct (upstream of the orifice) were measured. The following were found out. The strength and timing of a pressure pulse at the exit of the straight exhaust duct (upstream of the orifice) were, to some extent, controllable by varying the size of the orifice and the length of the straight exhaust duct. Smaller orifices made the operation stability of the multi-tube PDE lower. The back-pressurization of the PDE system was realized by high-frequency operation of a PDE with an orifice at the exit.
