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

ABSTRACT

In this paper, fluid flow and heat transfer characteristics are analyzed numerically for fluid flow past two elliptic cylinders arranged in a tandem manner. The numerical computation was performed using an in-house code based on the SUPG - FEM algorithm. Isothermal boundary condition is imposed on the surface of both the elliptic cylinders. Parametric studies are carried out by varying the axis ratio of the elliptic cylinders (AR = 0.5, 0.8, and 1.0) and distance between the two cylinders (L/D = 1.5, 2.0, 2.5, 3.5, and 5.0) for different Reynolds numbers (Re = 50, 100, 150, and 200). Parameters such as pressure coefficient, drag coefficient, lift coefficient, Strouhal number, and Nusselt number are calculated for all the cases. It is observed that the critical spacing ratio (distance between the cylinders at which the mean drag coefficient shows a sharp increase) of the cylinders shifts toward a lower value at Re = 200 for AR = 0.5 and 0.8. It is also found that for both the cylinders, convective heat transfer increases for elliptic cylinders with lower axis ratio (AR = 0.5 and 0.8). Finally, correlations are derived for mean drag coefficient and average Nusselt number as a function of Reynolds number, spacing ratio, and axis ratio.
