MHD Oblique Stagnation Point Flow of Nanofluid Over a Convective Stretching Surface

The present model demonstrates the analysis of non-orthogonal flow of electrically conducting nanofluid past a stretching surface with the existence of uniformly applied magnetic field. To sustain this heat transfer mechanism via hot fluid, we have considered the convective boundary conditions at the lower surface of the stretching sheet. By means of the similarity transformations, partial differential equations governing the model are converted into the system of nonlinear ordinary differential equations. Transformed system is tackled numerically by the shooting method. Moreover, the Matlab built-in routine bvp4c is used to validate and strengthen the numerical results obtained by the shooting method. The effect of different physical parameters e.g., non-orthogonality parameter, Brownian motion, Hartmann number, thermophoresis parameter, etc. is analyzed through graphs and tables. To analyze the fluid flow behavior, heat and mass transfer at the surface of the sheet, we calculate the numerical values for skin friction coefficient, local Nusselt and Sherwood numbers. Flow behavior of nanofluid is analyzed through the stream lines for both orthogonal and non-orthogonal cases.
