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

An external flow field of a single oscillator is characterized and the interaction characteristics of an array of oscillators in quiescent environment are studied in this experimental investigation. Time-averaged and phase-averaged velocity fields of a single oscillator are studied to characterize the external flow field. A spacing between the oscillators and volume flow rate were varied to study their effects on the jet interaction characteristics. Sweeping jet oscillation similarity was ensured using frequency characteristics of the oscillators. Two-dimensional particle image velocimetry (PIV) was used to characterize the external flow field. The method of zero-crossing was used for phase-averaging and the characteristics of the jet exiting from the oscillator at various phases were studied. The interaction height of the oscillating jets is influenced by the spacing between the oscillators and is found to increase with the spacing. The volume flow rate does not significantly affect the interaction height. The change in the spacing alters the deficit in the velocity between the peaks, while the change in the volume flow rate spatially shifts the profiles in the streamwise direction as the flow momentum is directly dependent on the volume flow rate. The deficit in velocity between the peaks increases with the spacing; however, an increase in the flow rate at the same spacing decreases this deficit.
