Abstract

Modeling for boundary layer stagnation point flow of Williamson fluid is developed. Electrically conducting liquid in presence of constant magnetic field is considered. Fluid is conducting. Induced magnetic field is accounted. Energy equation is modeled subject to radiative heat flux, heat source/sink and dissipation. Concentration equation for binary chemical reaction with activation energy is examined. Volumetric entropy rate is computed employing second law of thermodynamics. Nonlinear system numerically solved. Outcomes of velocity, temperature, entropy generation and concentration are carefully examined. Nusselt number and skin friction coefficient are numerically discussed. The obtained results are matched in an excellent manner.
