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

ABSTRAKT

The present work focuses on the study of an interesting topic from different points of view, that is, theoretical, practical, and numerical modeling. This study aims to improve the heat transfer within thermal devices like heat exchangers, solar air collectors, and other electronic equipment; these thermal devices play a major role in the industry these days. This work consists of a computational fluid dynamical analysis of a turbulent forced-convection constant property Newtonian fluid flow, in the presence of two differently shaped solid-type obstacles, that is, flat rectangular and V-upstream shaped, arranged in an overlapping manner, in a horizontal two-dimensional pipe of rectangular section. The effects of obstacle sizes and flow rates are analyzed. The Reynolds averaged Navier−Stokes equations with the standard k-ε turbulence model and the energy equation governing the problem are solved numerically by the finite volume method using the commercial CFD software FLUENT. The results are shown in terms of streamlines, mean velocity field, dimensionless axial velocity profiles, dynamic pressure, turbulent kinetic energy, turbulent intensity, fluid temperature, dimensionless temperature profiles, skin friction coefficients, local and average Nusselt numbers, and thermal enhancement factors.
