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: 1.5 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 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

SINOPSIS

An analysis is performed to study free convective boundary layer flow of second-grade fluid along an isothermal, impermeable sphere. The Clausius-Duhem inequality is used to describe the second-grade fluid, the presence at stress terms in momentum boundary layer equations. The governing boundary layer equations are transformed into nondimensional form by using specified nonsimilarity variables. A numerical solution is obtained by employing the validated, efficient, implicite finite difference method with Keller box scheme. A parametric study of physical parameters, Deborah number, and Prandtl number involved in the problem is conducted and a representative set of numerical results for velocity and temperature profiles as well as skin friction coefficient and Nusselt number are illustrated graphically and in tabular form. Comparisons with previously published work for different values of the physical parameter of the problem are reported and the existing results are found to be in excellent agreement. An increasing Deborah number retards the velocity and Nusselt number inside the boundary layer region while accelerating the temperature profile and skin friction coefficient. Increasing Prandtl number results in depreciation in the velocity, temperature profiles, and skin friction coefficient while the Nusselt number increased. Applications of the model arise in polymer processing in chemical engineering as well as metallurgical materials processing.
