Abstract
The prime intention of present article is to study the behavior of magnetized Williamson nanofluid. Flow governing model is obtained considering flow over variable thickness surface with convective heat and mass boundary constraints. The effects of Joule heating, Brownian diffusion and thermophoresis are further considered. Moreover, chemical reaction associated with activation energy is accounted. Boundary layer assumptions are used to obtain the dimensional system of differential equations. The system of PDE's are converted into ODE's ones using transformations. Magneto fluids are relatively prevalent in liquid metals, salt water, plasma, metallurgy, cancer therapy and drug delivery target. The considered investigation has relevance in metallurgical processes, polymer industry and plastic sheet. The governing model of ODE's is then tackled via HAM for convergent series solution. Influence of pertinent variables on velocity, concentration, temperature, total entropy rate, skin friction coefficient, Bejan number, local heat and mass transfer rates are studied graphically. Main outcomes are enlisted at the end.
