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

It is known that reverse flow (i.e., flow in the direction opposite to the free stream direction) occurs when an obstruction is placed near the entry to a channel (referred to as the test channel), kept inside another wider channel. The present investigation is focused on realizing a reverse flow in the test channel without an obstruction placed at the entry. Experiments in the water channel have been carried out along with flow visualization. The initial investigation revealed that reverse flow even in the absence of an obstruction would occur in a situation where the two walls, forming the channel have a stagger with respect to each other and are kept at an angle of attack. Studies have been carried out for different widths (i.e., gaps between the two walls forming the channel), stagger (i.e., perpendicular distance between the leading edges of the side walls), and angles of attack. It is found that both the stagger and the angle of attack are needed for reverse flow to occur. The critical angle of attack at which the reverse flow begins depends on the stagger and channel width.
