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

摘要

The evolution with time and space of hot gas (NOx, CO2, air) in exhaust underexpanded jet is studied by numerical simulations. The jet at the nozzle exit is at Mach number Mj = 1, the ambient flow corresponds to an homogeneous base state environment. This test case is considered to analyze turbulent motion responsible for gas mixing with ambient air. Longitudinal streamwise Taylor−Görtler eddies in mildly underexpanded jet are identified in our flow visualizations. A complete transition to turbulent flow is reached thanks to Monotone Integrated Large Eddy Simulation (MILES) approach. Computed statistics are in good agreement with experimental measurements.
