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

Airblast atomizers are used extensively in aero gas turbine engines. In the pursuit of reducing emissions and increasing fuel efficiency a novel airblast atomizer design is being developed that is capable of variable fuel-placement. Such a design will create two independently fuelled zones, a pilot and a main that can be optimised for fuel efficiency, emissions and stability throughout the flight envelope. The airflow and spray structure of three designs have been investigated experimentally using Phase Doppler Anemometry (PDA) to determine the size and direction of their respective recirculation regions. The experiments were performed isothermally and under atmospheric conditions. Axial air velocity profiles were obtained at a number of radial and axial positions downstream of the injectors. Findings show that all three devices have two independently fuelled regions and two of the devices have very similar flow structures despite their geometrical differences. The three airblast atomizers were also modelled using the commercial Computational Fluid Dynamics package (CFD) CFX. The devices were modelled isothermally in order to validate the CFD models using the PDA data. Qualitatively the CFD captured the flow profiles for the three devices, and there was also good quantitative agreement especially in the downstream regions for two of the devices.
