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

Temperature is the dominating parameter of combustion processes. To achieve realistic results, non-intrusive methods must be applied in measuring flame temperatures. This can be realized by quantitative analysis of the emitted radiation. One well-known technique to determine intensity distribution is emission spectroscopy. Typically, the flame spectra in the ultraviolet (UV, < 350 nm) and visible (VIS, < 750 nm) are governed by band profiles of diatomic molecules. To obtain information about the temperature from their intensity distribution, the experimental values are compared to corresponding calculated spectra.
Therefore different transitions of the most important diatomic molecules occurring in flames, like OH, NH, CN, CH, C2, CuH, MgO and AlO, have been calculated and intensity distributions modeled. In most cases, the calculated spectra showed only a small deviation from the observed experimental intensity distributions. To determine the combustion temperatures of different processes, recorded experimental spectra were compared to calculated data by a least squares fit routine with the parameter temperature and halfwidth of the line profile. The method was applied to solid propellant flames and rocket exhausts. The temperatures determined showed realistic values compared to those obtained in other studies. The possibility of using different radicals in the same flame allows a clearer discussion of the values achieved.
