摘要：

An investigation has been performed to analyze the impacts of Soret and Dufour on natural convective and heat absorbing flow of viscoelastic radiative nanofluid driven by a linearly stretched sheet considering inclined magnetic field. By making use of suitable linear transformations, the mathematical equations of problem are changed into the extremely non-linear coupled system of ordinary differential equations. Further, solutions of these differential equations are obtained by implementing GFEM (Galerkin finite element method). The consequence of various controlling pertinent parameters on nanofluid velocity, solutal concentration, temperature and nanofluid concentration are illustrated by means of various graphs while from engineering aspect numerical values of the shear stress, wall temperature gradient, solutal and nanoparticles concentration rate at the stretched sheet are presented in different tables. The numerical results are compared for mono and double diffusive nanofluids which yield that the aligned magnetic field, viscoelasticity, solutal and Brownian diffusivity have significant impacts on the flow field. The reliability of implemented method is authenticated by comparing our results with the previously published results under certain conditions, which signifies the correctness of the implemented method. The present investigation is applicable in several industrial processes such as coolant application, nano-drug delivery, cooling of microchip, heat exchanger technology, biological fluid movement and oceanography etc. © 2018 Trans Tech Publications, Switzerland.
