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

ABSTRACT

An experimental flow visualization has been carried out here to investigate the transient return flow formation in mixed convection of gas over a heated circular plate embedded in the bottom of a horizontal flat duct, simulating that in a horizontal longitudinal flow reactor. The results reveal that shortly after the transition is started the forced flow is first reversed by the buoyancy force to move upstream in the region near the duct sides just above the outer edge of the heated plate and there are two small return-flow zones in the duct. Then, the forced flow over the entire upstream edge of the heated plate is reversed. Because of the circular geometry of the heated plate, a semicircular return-flow zone appears surrounding the whole upstream edge of the heated plate. This upstream return flow later gradually approaches a steady state. Besides, a downstream unsteady return-flow zone that appears slightly later than the upstream one is also observed in the duct. The two return-flow zones do not contact with each other.
