Analysis of Williamson Fluid of Hydromagnetic Nanofluid Flow in the Presence of Viscous Dissipation over a Stretching Surface Under Radiative Heat Flux

The consequence of magnetic field and thermal radiation over temperature-dependent viscosity are the area that grabs the attention of researchers due to their wide applications in industries. This paper discussed the same for the unsteady nanofluid boundary layer flow of an incompressible Williamson fluid. We assumed a stretched surface in the presence of radiative heat flux and porous medium. The governing equations are transformed into the nonlinear system of ordinary differential equations which are further solved numerically by the Spectral Quasi Linearization Method (SQLM). The physical effects are graphically discussed and calculated on different parameters like velocity, temperature, and concentration. Some more parameters like skin friction coefficient and local Nusselt number are presented and examined mathematically. The rise of the heat generation parameter and the thermal Biot number enhances the heat profile of the fluid while the solutal concentration falls for the higher values of the solutal Biot number. The correlation coefficient and probable error are also calculated to check the significance and insignificant relation of parameters with skin friction and Nusselt number.
