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

摘要

This paper presents the longitudinal dispersion of passive contaminant released in an incompressible viscous fluid flowing between two infinite parallel plates, where the contaminant undergoes irreversible heterogeneous reaction with the boundary walls. The flow is driven by the oscillation of the upper plate in its own plane with a constant velocity as well as by an imposed constant pressure gradient. This type of flow may be termed unsteady generalized Couette flow. A finite difference implicit scheme has been adopted to solve the unsteady convection-diffusion equation for all time periods based on the Aris method of moments. The influence of applied constant pressure gradient, oscillation of the upper plate, and the absorption parameter at both walls on dispersion is discussed. The dispersion coefficients are obtained for three different flow situations: plane and generalized Couette flow, unsteady generalized Couette flow, and for comparison, the combined effect of steady and unsteady Couette flows, separately. The most striking result is that unlike the case of parallel flow under periodic pressure gradient, the double-frequency period in the dispersion phenomena does not vanish, even for the high frequency of upper-plate oscillation for the case of unsteady generalized Couette flow. The axial distributions of mean concentration are determined from the first four central moments using Hermite polynomial representation for the periodic flow with or without nonzero mean flow.
