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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRACT

Local heat transfer coefficients were measured in the separating, reattaching and redeveloping axisymmetric regions of turbulent boundary layer over the wall of convex cylinders with a uniform wall heat flux. Measurements were made with three different diameters of cylinders with five different diameters of the obstructions. The range of Reynolds number based on step height was between 4000 to 100000.
The study demonstrates that the maximum Nusselt number increases with decreasing cylinder radius and are always greater than those for the two-dimensional backward-facing step flow at the same conditions of the step height and flow velocity. It was also observed that the heat transfer in the redeveloping region increases with an increase in the radius convex curvature. An empirical equation is proposed for the Nusselt number at the reattachment point, correlated as a function of the Reynolds number and the diameter ratio.
