A Numerical Study of Magnetohydrodynamic Stagnation Point Flow of Nanofluid with Newtonian Heating
In this study we have explored the numerical solution of MHD stagnation point flow of an incompressible nanofluid towards a stretching surface effected by Newtonian heating. The obtained model of non linear partial differential equations is converted into a set of ordinary differential
equations using an appropriate transformation. Shooting method is employed to solve the said system of boundary layer equations. Discussion of momentum, temperature and concentration profiles against emerging parameters like Prandtl number Pr , Brownian motion parameter Nb, thermophoresis
parameter Nt, Lewis number Le, stretching parameter ε and conjugate parameter γ is added to the text with graphical illustrations. Tabulated values of local Nusselt number and sherwood number is an added feature with detailed discussion against different
pertaining parameters. It is observed that Temperature profile (η) is higher for large values of Brownian motion parameter Nb and thermophoresis parameter Nt. It is also found that for increasing values of Hartman number M and ratio parameter
ε, skin friction coefficient show increasing and decreasing behavior respectively.
