MHD Williamson nanofluid flow past a permeable stretching sheet with thermal radiation and chemical reaction

Heat and mass transmission of non-Newtonian fluids get considerable attention due to their complexity and high nonlinearity in rheology. Among the various fluid models, Williamson fluid model very well describes the low as well as high-viscosity situations. With this perspective, the present work deals with heat and mass transfer of MHD Williamson nanofluid flow past a porous stretching surface with thermal radiation and chemical reaction. Highly nonlinear governing equations are transformed into ordinary ones by employing similarity invariants. The reduced systems of ODEs are numerically treated with R-K’s fourth-order method along with the shooting technique. Using MATLAB the associated nondimensional parameters are graphically interpreted and found to be in good agreement with the literature. For the higher values of magnetic and Williamson parameters, fluid motion becomes a decreasing function whereas the temperature profile is enhanced for the magnetic, Williamson, and radiation parameters. The investigation will serve in the process involving fluids such as food processing, glass manufacturing, oil extraction, etc.
