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

RESUMO

Flow hydrodynamics of laminar falling film of aqueous Li Br solution (Li Br − H2O) on a horizontal elliptical tube has been investigated in this research. The film velocity distribution and film thickness, namely, the flow characteristics are determined by solving analytically simultaneous simplified Navier − Stokes equations and continuity equation in polar and Cartesian coordinates. The analysis is based on steady state laminar flow of falling liquid film of Li Br − H2O on a horizontal elliptical tube in polar model and Cartesian model (CM), for cases in which traction on the film surface is considered negligible. Models are compared with each other in three cases of aspect ratios (Ar), tube diameters, flow rate, mass concentration and temperature of solution. The flow characteristics values in Cartesian model are over predicted with respect to polar model. The results show that the error in Cartesian model with smaller tube diameter is increased as mass flow rate increases. In Cartesian model, the aspect ratio and tube diameter show no effect on flow characteristics values around the elliptical tube. Therefore, as the eccentricity of ellipse (the ratio of the ellipse focal separation to the major axis) in the elliptical tube increases, the error increases as well. Finally the flow characteristics around horizontal elliptical tube with Ar > 1 are showing better performance with respect to flow characteristics around horizontal elliptical tube with Ar < 1.
