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

In this paper, we present a numerical solution for heat transfer in the flow of a non-Newtonian power law fluid immersed in a saturated porous medium over a nonisothermal stretching sheet in the presence of internal heat generation/absorption. Thermal conductivity is assumed to vary as a linear function of temperature. Similarity transformations are used to convert highly nonlinear partial differential equations into ordinary differential equations. The resulting coupled nonlinear ordinary differential equations are solved numerically by the efficient Keller box method for two different cases, namely, a surface with prescribed surface temperature and surface with prescribed wall heat flux. The important findings of our study are that the effect of the power law index is to decrease the horizontal velocity boundary layer thickness and thermal boundary layer thickness. The effect of the porous parameter is to reduce the horizontal boundary layer thickness and increase the thermal boundary layer thickness.
