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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

Experiments were performed using n-heptane droplets burning in air under microgravity conditions in the 2.2 second droptower at NASA-Lewis Research Center. This study demonstrates the effects of pressure on the sooting behavior for droplet flames under microgravity conditions. The transient soot concentration distributions were measured by using a full-field light extinction technique and subsequent tomographic inversion.
The effective control of sooting and the accurate measurement of its magnitude are important for assessing the importance of sooting and radiation on the burning characteristics of droplets. Results indicate that sooting within the droplet flame is sensitive to the ambient pressure. Possible reasons for the reduction of soot concentrations include the reduction in the flame temperature and reduction in residence time for fuel vapor transport within the fuel-rich region.
