  We study steady streaming in a channel between two parallel permeable walls
induced by oscillating (in time) blowing/suction at the walls. We obtain an
asymptotic expansion of the solution of the Navier-Stokes equations in the
limit when the amplitude of the normal displacements of fluid particles near
the walls is much smaller that both the width of the channel and the thickness
of the Stokes layer. It is demonstrated that the magnitude of the steady
streaming is much bigger than the corresponding quantity in the case of the
steady streaming produced by vibrations of impermeable boundaries.
