Magnetohydrodynamic Flow Past a Finite Flat Plate in the Presence of a Nonaligned Magnetic Field

Abstract

We consider the steady flow past a finite flat plate due to a uniform stream in the presence of a uniform magnetic field which is not aligned with the streaming motion at infinity. The Hartmann number is assumed large and positive. This leads to a singular perturbation problem involving a second-order partial differential equation. As a result, solutions of the governing equation must be obtained in three separate regions and then matched asymptotically. A related problem involving magnetohydrodynamic (MHD) flow across a finite needle is also discussed.
