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 use of pressure swirl injectors in wall-guided spark ignition direct-injection engines has emerged as a potential solution to decrease the specific fuel consumption of conventional port fuel injection systems. A major hurdle in the use of these injectors is that the spray characteristics, like the cone angle and drop sizes, are sensitive to the operating conditions, especially when the fuel undergoes a phase-change process inside the nozzle. This phase-change process, when driven by thermal effects, is known as flash boiling. A precise control of this mechanism can be used to achieve a well-atomized spray with higher cone angles and smaller drop sizes. However, such control is extremely difficult considering the highly transient nature of the phase-change process. An accurate modeling of flash boiling is critical if these injectors are used in practice. As this phenomenon is mainly driven by interphase heat transfer and has a time scale that is comparable to the flow-through times in the system, a finite-rate model should be employed for these simulations. In this work, the homogeneous relaxation model was used to conduct transient, three-dimensional simulations of a pressure swirl injector. The working fluid used in the calculations is n-hexane and all its thermophysical properties are obtained from NIST databases. The geometry includes the inlet swirl ports, the swirl chamber, the injector nozzle and the combustion chamber. A parametric study under four different operating conditions has been conducted and qualitative comparisons with experiments are presented.
