On the numerical solutions of three-dimensional MHD stagnation-point flow of a Newtonian fluid

In this paper the steady three-dimensional stagnation-point flow of an incompressible, homogeneous, electrically conducting Newtonian fluid over a flat plate is investigated numerically. The fluid is permeated by a uniform external magnetic field H_0. The effects of the magnetic field on the velocity profiles are presented graphically and discussed. This paper completes the analysis concerning the Newtonian fluids devoleped in [4]. The obtained results indicate that the thickness of the boundary layer decreases when the magnetic field increases. Moreover H_0 tends to prevent the occurrence of the reverse flow. By virtue of the numerical integration, the stagnation-point is classified as nodal or saddle point and as attachment or separation point.
