Flow around a sphere in an oscillating stream of a dusty fluid

The oscillation of a stream of dusty fluid in the presence of a sphere has been discussed. The effect of interaction of curvature
and viscosity has been included in the boundary layer equations. The dust particles slip on the surface of the sphere and the slip
velocity is a function of relaxation time of the dust particles but is independent of mass concentration of the gas. Dust particles shift the steady secondary flow towards the main flow and increase the resistance on the sphere.
