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: 2.3 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: 1.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 1 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: 0.00067 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: 0.47 SJR: 0.282 SNIP: 0.632 CiteScore™:: 3 H-Index: 42

要約

This work presents a numerical analysis of the time-dependent three-dimensional hydromagnetic Casson fluid flow along a stretching surface through a porous medium considering the effects of Hall current and nonlinear radiation. The mathematical model of the problem is presented in the form of a set of nonlinear partial differential equations along with suitable boundary conditions. These equations are transformed to a set of nonlinear ordinary differential equations using suitable similarity transformations which are later dealt with the efficient spectral quasi-linearization method (SQLM) to obtain the numerical solution of the considered model. A parametric study involving the emerging physical parameters is performed to analyze the effects of relevant flow parameters on the fluid velocity, fluid temperature, and coefficients of skin-friction and heat transfer at the surface. It is found that the momentum boundary layers, in both directions, get thicker whereas the thermal boundary layer becomes thinner with increasing Hall current.
