Abstract

In this paper a similarity analysis is made for the forced and free convection boundary layer flow in a semi-infinite expanse of an electrically conducting viscous incompressible fluid past a semi-infinite non-conducting porous plate with suction. A uniform magnetic field is applied normal to the plate. A time dependent suction is also introduced. The governing equations of the problems are then reduced to linear similarity equations, which are made local by introducing suitable similarity parameters. These local similarity equations are solved numerically by an adapting shooting method which uses the Nachtsheim-swigert interaction technique. Effects of various parameters on the velocity and temperature fields across the boundary layer are investigated. Numerical results for the velocity and temperature distributions are shown graphically.
