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

Effect of Reynolds number and horizontal offset for a fixed vertical offset has been investigated for a double offset S-shaped circular diffusing duct using a CFD code FLUENT. The investigations have been carried out for a fixed geometry using different turbulence models and it is observed that the RNG turbulence model gives the closest matching with experimental results. Investigations have shown that at high Reynolds numbers (≈ 106), there is no effect of Reynolds number on the performance of the diffuser. Secondary flow distribution has shown the formation of two pairs of contra rotating vortices at the exit plane and beyond. The core of the flow moves along the diagonal plane which is inclined to vertical axis at an angle determined by the magnitude of horizontal offset i. e. 15°/15° offset gives an angle of 30° whereas 30°/30° offset gives an angle of approximately 60°.
