Abstract

Abstract: This communication elaborates non-linear convection and heat sink/source effect in stretchable flow of Williamson fluid. Hydromagnetic laminar flow is examined. Heat-mass transport attributes are addressed via improved Fourier-Fick formulas. Conductivity and diffusivity of fluid depend on temperature and concentration. First-order chemical reaction aspect is also a part of current study. The concept of boundary-layer pioneered by Prandtl is utilized in order to simply the non-linear problems which are then reduced to the ordinary differential systems. Homotopy algorithm yields convergent outcomes of ordinary systems. A detailed analysis describing physical importance of pertinent variables is presented. Besides the obtained analytical outcomes are compared with the available numerical/exact outcomes and reasonable agreement is witnessed.
