The flow generated by a circular cylinder, performing longitudinal and
torsional oscillations, in an infinite expanse of a micropolar fluid is
studied. Analytical expressions for the velocity and micro rotation
components are obtained using no slip and hyper stick conditions at the
boundaries. The effects of coupling number; Reynolds number and gyration
parameter on the transverse and axial velocity components are shown and
explained graphically. Also explicit expression for the drag force acting on
the wall of the cylinder is derived and the effects of pertinent parameters
on the drag are shown graphically.
