Abstract


The analytical solution is made on the unsteady flow of an electrically conducting viscous incompressible fluid bounded by an infinite vertical
porous plate. The plate executes harmonic oscillation at a frequency nin its own plane. The governing equations of the problem contain
coupled partial differential equations. The dimensionless equations are solved analytically using perturbation technique. The effect of various
parameters of the problem on the velocity, temperature and concentration field within the boundary layer are discussed and shown graphically.


Keywords


MHD flow, Hall current, Ion-slip current, Suction parameter, Heat source parameter.
