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: 1.2 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: 1.8 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

摘要

Fuel atomization and droplet dispersion play vital roles for achieving efficient combustion inside a spray combustor. In the present study, a novel atomizer is developed which employs a rotating spindle with blades at the orifice exit to atomize the fuel into a fine spray. Important spray characteristics such as spray cone angle and Sauter mean diameter (SMD) are measured using a high-speed camera and a phase Doppler interferometer (PDI). This atomizer provides uniform fine sprays even at very low pressures of the order of 1 bar. The droplet size distribution and dispersion exhibit only minor dependence on the fuel flow rate or injection pressure. Criteria have been identified for three different liquid break up modes, namely, jet break up, sheet break up, and direct drop formation. Useful correlations for evaluating the spray droplet size (SMD) are presented in terms of the swirl number of liquid flow, rotational speed based sheet Weber number, and swirl air Reynolds number.
