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

要約

The effects of recess length in a liquid-centered swirl coaxial injector on the spray characteristics have been investigated using a Dantec phase Doppler anemometry (PDA) system and a Photron Fastcam SA-1.1 camera. The spray cone angle and droplet Sauter mean diameter (SMD) were characterized at predefined recess lengths and pressure drops. It is found that recess is the key geometrical parameter to excite self-pulsation for the given gas and liquid mass flow rates. Once the recess length approaches or exceeds a critical value which is related with the spray cone angle of liquid pressure swirl injector, self-pulsation is excited, and the spray cone angle increases significantly. With further increase of recess length, the spray cone angle of both stable spray and self-pulsated spray decreases gradually. The drop size and its distribution are heavily influenced by both recess length and gas-to-liquid mass ratio (GLR). When the GLR is relatively low, with the increase of recess length, the global Sauter mean diameter (GSMD) of the spray increases gradually and SMD distribution varies from a 'Λ' shape to a hollow cone shape. However, when the GLR is large enough, with the increase of recess length, the GSMD increases slightly at the beginning of self-pulsation and then decreases gradually, and the distribution of SMD shows a slant 'N' shape for both stable and self-pulsated sprays. Independent of recess length, the GSMD of the spray decreases with GLR.
