Magnetohydrodynamic oblique stagnation-point flow. (English) Zbl 1258.76200

Summary: Laminar two-dimensional stagnation flow of a viscous and electrically conducting fluid obliquely impinging on a flat plate in the presence of a uniform applied magnetic field is formulated as a similarity solution of the Navier-Stokes equations. The relative importance of this flow is measured by the dimensionless strain rate and magnetohydrodynamic parameters \( \gamma \) and \( M \). The viscous problem is reduced to a coupled pair of ordinary differential equations governed by \( \gamma \) and \( M \). It is found that the parameter \( M \) causes a shift in the position of the point of zero skin friction along the wall.
