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

摘要

A key requirement for catalysts used for space propulsion applications is, amongst others, a rapid response time. This is often assessed in terms of how long it takes for a thruster to reach 95% of the steady-state thrust or pressure from the moment the flow valve is opened. Equally important, however, is to assess what the average lifetime of a pocket of fluid entering the catalyst bed is. To this end, a set of four different 3D-printed catalysts was subjected to a flow of highly concentrated hydrogen peroxide. The effectiveness of the catalyst was assessed with respect to the amount of liquid present during steady-state operation. To assist the assessment, a simple depletion model was developed. For this purpose, four different gas-to-liquid conversion models were employed. It was found that the model produces accurate results for about 65% of the initial depletion of the decomposition chamber. Given the layout of the system that was used for testing, it is believed that one of the key assumptions, namely that no liquid is entering the decomposition chamber anymore, is not entirely met. Based on only the first 65% of the depletion process, it was estimated that between 18 and 29% of the accessible decomposition chamber volume is occupied by liquid during steady-state operation.
