Radiative Williamson nanofluid flow over a convectively heated Riga plate with chemical reaction-A numerical approach

This exploration studies the effects of chemical reaction and thermal radiation on the flow of a Williamson nanofluid over a convectively heated Riga plate with variable thickness. Mathematical modeling is developed considering heat generation/absorption with the effects of Brownian motion, thermophoresis and a slip condition. A newly suggested zero mass flux condition has also been introduced in the present study. Numerical solution of the non-linear differential equations is achieved by employing the shooting method. Graphical illustrations depicting the effects of the sundry parameters on the velocity, temperature and concentration fields are also presented. Numerically calculated values of the skin friction, local Nusselt and Sherwood numbers with the requisite discussion are also presented. It is seen that the concentration profile is a decreasing function of the chemical reaction and Brownian motion parameters. (C) 2017 The Physical Society of the Republic of China (Taiwan).
