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

RÉSUMÉ

Fluid flow in micro-channel is a major area of research, due to its wide area of applications in various forms in industries. Although substantial works have been carried out experimentally, numerically as well as analytically in this area, still the reported results show a wide variation from one another. In the present work, an attempt has been made to consider the problem of gas flow in circular micro-channel under conditions of varying Knudsen number (Kn = 0.001–0.1), which corresponds to continuum model. The observation is confined to the laminar zone only and fluid properties have been assumed to be constant. The momentum equation has been converted into stream function-vorticity form and a finite difference technique has been used. Both slip and no-slip boundary conditions have been applied. The numerical scheme has been validated and the results have shown the importance of the Knudsen number on friction factor Reynolds product, pressure distribution in the gaseous flow during its hydro-dynamically developing stage. Also, a non-dimensional analysis has been presented.
