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

SINOPSIS

Across the world several so-called green propellants for in-space and orbital propulsion are investigated to replace the highly toxic hydrazine. Aside from green alternatives based on ADN and H2O2, the DLR Institute of Space Propulsion examines a premixed propellant consisting of dinitrogen monoxide (N2O) and ethene (C2H4). The mixture called HyNOx (hydrocarbons mixed with nitrous oxide) offers high performance and low toxicity, but due to the premixed state, the danger of flame flashback across the injection system is a major issue. To avoid flashback during operation of a future engine, suitable flashback arresters are needed; thus, the quenching diameters and corresponding quenching Peclet numbers have to be derived. To analyze the quenching diameters, DLR uses an ignition and flashback test setup. The setup consists of two chambers separated by a fitting for capillaries which serve as flashback arresters. Capillaries with diameters between 0.1 and 0.5 mm were examined regarding their ability to quench the flame. Furthermore, one chamber can be equipped with glass windows to record high-speed videos of the flame propagation process. To obtain the critical quenching Peclet number the ignition pressure was consecutively raised until a flame flashback for a given capillary was observed. The quenching Peclet numbers were calculated according to the gas state at ignition. This resulted in critical Peclet numbers between 30 and 40. Additionally, high-speed videos were recorded to analyze the flame propagation speed during the combustion process. The average flame propagation speed was between 33 m/s for an ignition pressure of 0.49 bar and 40 m/s for an ignition pressure of 1 bar.
