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

ABSTRACT

Prediction of far field noise radiation from high speed jets depends upon the accurate computation of the unsteady jet flow features and preserving the wave-like character of such features. It is particularly critical that these features be preserved as the disturbances pass through the computational boundaries. The present effort is directed toward examining various formulations based on the method of characteristics for outflow boundaries. Small harmonic disturbances are introduced at the inflow and the computed results for the growth of the input disturbance are compared against that of linear stability theory using three different outflow boundary conditions in a Navier-Stokes code. Another issue of importance examined in this study is the influence of proximity of the outflow boundary (or length of the computational domain) relative to the jet diameter.
