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

RÉSUMÉ

This article investigates rotational effects on secondary flow and heat transfer in rotating flow passages with sudden expansion. Consideration is given to steady-state incompressible laminar flow. The governing equations are discretized by means of a finite-difference technique and numerically solved to determine the distributions of velocity vector and fluid temperature under the appropriate boundary conditions. The Reynolds number and rotation rate are varied to determine their effects on both the formation of secondary flows and the heat-transfer performance in the sudden expansion region. It is disclosed from the study that: (1) for a laminar flow in a pipe with sudden expansion, axial rotation causes the secondary flow zone to stretch and amplifies the heat-transfer performance in the expansion region, and (2) the elongation of the secondary flow zone and heat-transfer performance are enhanced with an increase in both the rotation rate and the Reynolds number. Results may find applications in automotive and rotating hydraulic transmission lines.
