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: 1.5 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 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

RÉSUMÉ

Fluid-structure interaction (FSI) of thin flexible plates involving large-scale flow-induced deformation is presented as a potential heat transfer enhancement technique. An in-house, strongly-coupled FSI solver is employed in which flow and structural solvers are based on sharp-interface immersed boundary and finite-element methods, respectively. Twin deformable thin plates in a heated channel are considered with laminar pulsating flow. Numerical simulations show that the vortex ring past the plates sweeps higher sources of vorticity generated on the channel walls out into the downstream−promoting the mixing of the fluid. The moving plates assist in convective mixing, augmenting convection in bulk and at the walls; thereby reducing thermal boundary layer thickness and improving heat transfer at the channel walls. The thermal augmentation is quantified in terms of instantaneous Nusselt number at the wall. Results are presented for two limiting cases of thermal conductivity of the plate−an insulated plate and a highly conductive plate. We discuss the feasibility and effectiveness of deformable plates and discuss the effect of important problem parameters−Young's modulus, flow frequency, and Prandtl number−on the thermal augmentation.
