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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

摘要

This study numerically analyzes transient multi-shock flow phenomena in a full-reflection shock tunnel using CFD. Based on the finite volume method, the compressible Navier-Stokes equations are solved with the upwind Roe's scheme and the total variation diminishing (TVD) scheme. To consider the real gas effect, the polynomial correlations of Tannehill and Mugge are applied to modify the equation of state in simulating the hypersonic environment. For either a perfect or viscous flow with the real gas effect, the flow features of the shock train, reflected shock wave/boundary layer interaction in the shock tube, and the Mach reflection configuration in startup process of nozzle flow are clearly observed in this work. The effect of the half-nozzle angle on the startup process of nozzle flow is also explored. The flow establishment time from placing a spherical model in the test section is 8.0 ms, and the effective flow test time is 3.5 ms.
