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: 2.3 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: 1.8 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: 0.2 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

RÉSUMÉ

In this study, an unsteady two-dimensional flow through parallel isoflux plates is numerically investigated. The effects of the frequency and amplitude variations of the pulsating flow on the flow field and convective heat transfer at a Reynolds number of 1000 are studied. In order to solve the Navier−Stokes and energy equations, the finite volume approach with a staggered grid is employed. Diffusion and convection terms in the momentum and energy equations are discretized using the central-difference scheme and the semi-fractional step method (revised step method of Kim and Moin [1985]) is used to solve the Navier−Stokes equations. The results indicate that the reattachment length increases by inserting a second plate parallel to the flow and the mean pressure coefficient increases due to the impact of this plate. Pulsating flow enhances the heat transfer from the parallel plate by reducing the reattachment length over the surface of the plates. The small vortex cores, created over the plate surfaces, merge together and produce a large vortex core at a high amplitude and frequency which decreases the convective heat transfer from the plates.
