Framing the novel aspects of irreversibilty in MHD flow of Williamson nanomaterial with thermal radiation near stagnation point

Here, MHD stagnation point flow of non-Newtonian fluid over a stretchable surface is considered. Process of modeling is characterized for basic relations of non-Newtonian Williamson fluid. Nanofeatures for thermophoresis and random movement of liquid particles present. Applied magnetic field for small Reynolds number is considered. Induced magnetic field is not accounted. Entropy equation is studied in the presence of Ohmic heating, radiation and dissipation. The carried out analysis reduces the PDE systems into the ODE systems with nonlinearity. The obtained nonlinear ODE systems are solved utilizing modern way of solution technique known as the built-in-Shooting method. Furthermore, total entropy rate is calculated via second law of thermodynamics. Velocity, entropy rate, temperature, Nusselt number, mass concentration, skin friction and Sherwood number are discussed through different physical parameters. Key observations of the whole study are listed.
