| Summary: | In order to determine the characteristics of peristaltic
transport of magnetohydrodynamic flow through a porous medium,
the motion of a hydromagnetic (electrically conducting), viscous,
and incompressible fluid in planer channel filled with a
homogeneous porous medium and having electrically insulated walls
that are transversely displaced by an infinite, harmonic
travelling wave of large wavelength was analyzed using a
perturbation expansion in terms of a variant wave number. We
obtain an explicit form for the velocity field, a relation between
the pressure rise and flow rate, in terms of Reynolds number,
wave number, Hartmann number, permeability parameter, and the
occlusion. The effects of all parameters of the problem are
numerically discussed and graphically explained. |
