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

In the present study, the unsteady laminar heat and mass transfer in incompressible micropolar boundary layer flow from a porous stretching sheet with variable suction has been examined. The unsteadiness in the flow, temperature, and concentration fields is caused by the time dependence of the stretching velocity, surface temperature, and surface concentration. By using a similarity transformation the governing time-dependent boundary layer equations with appropriate boundary conditions are rendered into a set of nonlinear ordinary differential equations. The dimensionless governing equations are then solved numerically by using the finite-element method. The effect of the suction parameter, unsteadiness parameter, coupling constant parameter, and Schmidt number on the distributions of the velocity, microrotation, temperature, and concentration functions are examined at length. The skin friction, wall heat transfer rate, and wall mass transfer are also computed. Under special cases, comparison of the flow velocity and rate of heat transfer is made with the exact solution and also with numerical results available from the literature. An excellent agreement between the results is obtained. Furthermore, validation of the present finite-element solutions is also achieved with a second-order-accurate finite-difference method outlined in the literature. In addition, the convergence of the finite-element numerical solutions is discussed explicitly. The study is relevant to materials-processing technology.
