Abstract
The two-dimensional flow of a dusty fluid induced by sinusoidal wavy motion
of an infinite wavy wall is considered for Reynolds numbers which are of magnitude
greater than unity. While the velocity components of the fluid and the dust particles
along the axial direction consist of a mean steady flow and a periodic flow, the
transverse components of both the fluid and the dust consist only of a periodic
flow. This is true both for the outer flow (the flow beyond the boundary layer) and
the inner flow (boundary layer flow). It is found that the mean steady flow is
proportional to the ratio
