Nonlinear Thermal Radiation, Heat Generation/Absorption and Chemical Reaction Effects on Hydromagnetic Williamson Nanofluid Flow over a Stretching Sheet

Abstract

In this paper, we have examined the two-dimensional flow of hydromagnetic Williamson nanofluid over a stretching sheet under the effects of nonlinear thermal radiation, heat generation/absorption and chemical reaction. The governing equations are converted into nonlinear ordinary differential equations by using similarity transformations and solved numerically by the in-built function bvp4c in MATLAB software. Furthermore, the effects of the physical parameters like nondimensional Williamson parameter, Lewis number, Schmidt number, Prandtl number, Magnetic field parameter, Darcy number and nanoparticle parameters (diffusivity ratio and heat capacities ratio) have been studied. The expressions for coefficients of skin friction, Nusselt number and Sherwood number have been derived and computed. The influence of various physical parameters over a velocity, temperature and concentration profile are presented with the help of graphs & tables and discussed.
