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

RESUMO

In this paper, the performance simulation of a sudden expansion diffuser and a hybrid diffuser has been carried out. The two-dimensional steady differential equations for conservation of mass and momentum have been solved for Reynolds numbers ranging from 50 to 600. During the simulation, a fixed aspect ratio of 2 has been considered for both diffuser geometries, and a fixed value of half divergence angle of 3.5° has been considered for the hybrid diffuser. At the inlet, a fully developed velocity profile has been used. The effect of Reynolds number on streamline contours and average static pressure has been studied in detail and compared between two diffuser geometries. The effective diffuser lengths for achieving maximum average static pressure at the diffuser exit have been computed for the considered Reynolds numbers.
