Numerical Aspects for Chemical Reaction on MHD Stagnation Point Flow of Williamson Nanofluid Under the Effect of Buoyancy Forces

Mathematical erection for magnetohydrodynamic (MHD) mixed convection flow of Williamson nanofluid near the stagnation point on a stretching sheet is introduced in this article. Newtonian heating and mass situations are considered in structure of radiation and chemical reaction. Thermophoresis and Brownian motion are established owed to nanoparticles. Transformation technique utilized yields nonlinear differential equations. Results are acquired through the bvp4c technique. Graphs are sketched to see the behavior of physical parameters. The effect of fluid parameter and Hartman number is quite similar. Mixed convection parameter enhances the buoyancy forces so relative velocity field boost. For ratio parameter A, we examine three cases, i.e., A < 0, A > 0 and A = 0. For each case, we see a different behavior of velocity profile. Also, we observe that lager R enhances the heat flux, whereas larger Prandtl leads to low thermal diffusivity. Greater Nb enhances the random motion of nanoparticles that boost the collision of particles. Numerical values of skin friction coefficient, Nusselt and Sherwood numbers are calculated and studied. Heat transfer rate and thermal field are quite reverse via thermophoresis parameter. Velocity field declines for greater Weissenberg number. Enhancement in Brownian motion parameter yields temperature enhancement. Concentration field is diminished via chemical reaction parameter. Thermal conjugate parameter tends to increase the temperature and heat transfer rate.
