Influence of thermal and concentration gradients on unsteady flow over a stretchable surface
Özet
The aim of this letter is to investigate the unsteady flow of incompressible fluid in the presence of thermal and concentration gradients over a bi-directional stretchable flat sheet that placed in nonporous media. The nondimensional form of the model is successfully obtained after utilizing the set of similarity transformations and necessary mathematical calculations. Then, resulting two-point boundary value problem is sort out numerically with the help of Runge-Kutta scheme after reducing the flow model into a set of initial value problem. Influence of the various flow parameters on the velocity, thermal and concentration fields discussed comprehensively by means of graphs. Furthermore, quantities of practical and physical interest such as skin friction coefficient, local rate of heat and mass transfer studied with the help of graphical aid. Finally, major outcomes of the study highlighted in the last section of the manuscript. (C) 2017 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND license.
