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

SINOPSIS

This article reports on the spatial−temporal instability behavior of a supercritical shear layer considering the real-gas effect. The dispersion relation governing the pressure perturbation was obtained and utilized to study the spatial−temporal instability of a shear layer. The dispersion relation was solved using a shooting method. The results are presented with a view to the effects of temperature ratio, velocity ratio, oblique angle, and Mach number. It is shown that in some cases, the variation of dimensionless numbers would lead to a transition between absolute and convective instability. A large value of temperature ratio or velocity ratio would enhance absolute instability; that is, increased temperature ratio or velocity ratio can make the supercritical shear layer transit to absolutely instability. Study of the effects of the oblique angle of disturbance waves shows that in spatial−temporal mode, three-dimensional disturbances dominate over two-dimensional disturbances. Increased compressibility would damp the absolute instability of a supercritical shear layer.
