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

SINOPSIS

Wettability is a fraction of wetted area on tubes by a film flow. In this study, the wetting characteristics of falling film on the horizontal tube are numerically investigated. The wetting characteristics are dependent on the properties of the liquid and flow regime especially in droplet and droplet to jet mode. However, experimental efforts observed in the literature are based on the measurement of mass flow rate and it is difficult to record wettability of tube. The objective of this paper is to record wettability of tube using numerical simulation. A numerical study is carried out using a computational fluid dynamics (CFD) code for 3D configuration considering geometrical and thermophysical parameters using volume of fluid model in Fluent 6.0. Commonly used fluids of modified Galileo number in the range of 36 to 552 are used for numerical simulation. In the current study, correlations of wettability measurement for smooth and rough surface are introduced. The results based on the generalized proposed correlations are validated with the experimental studies. It is observed that wettability increases with mass flow rate and diameter of tube and is maximum for high viscous fluid.
