MHD Stagnation Flow of a Newtonian Fluid towards a Uniformly Heated and Moving Vertical Plate

Abstract

Stagnation flow of an electrically conducting incompressible viscous fluid towards a moving vertical plate in the presence of a constant magnetic field is investigated. By using the appropriate transformations for the velocity components and temperature, the partial differential equations governing flow and heat transfer are reduced to a set of nonlinear ordinary differential equations. These equations are solved approximately using a numerical technique for the following two problems: (i) two-dimensional stagnation-point flow on a moving vertical plate, (ii) axisymmetric stagnation-point flow on a moving vertical plate. The effects of non dimensional parameters on the velocity components, wall shear stresses, temperature and heat transfer are examined carefully.
