Induced Magnetic Field on Williamson Fluid Past a Stretching Surface with Nonlinear Thermal Radiation and Non-Uniform Heat Source or Sink

Abstract

In this study, we investigated the effects of induced magnetic field and nonlinear thermal radiation on Williamson nano fluid past a stretching surface in the presence of non-uniform heat source/sink. The transformed governing equations are solved numerically using Runge-Kutta based shooting technique. We acquire better accuracy of the present results by comparing with the published literature. The influence of dimensionless parameters on velocity, temperature and concentration profiles along with the friction factor coefficient, the heat transfer rate and the mass transfer rate are discussed with the help of graphs and tables. It is found that the heat transfer rate in Williamson fluid is high while compared with the Base fluid.
