Summary: The steady flow of a micropolar fluid over a finite rotating disc enclosed within a coaxial cylindrical casing has been studied. The governing equations were solved numerically by using the finite element method. Maximum values $\xi _{1}$ and $\xi _{2}$ of the dimensionless radial distance at which there is no-recirculation for the cases of net radial outflow and net radial inflow respectively, increase with an increase in the micropolar effects. The velocities at $\xi _{1}$ and $\xi _{2}$ as well as at some fixed radii have been calculated and the associated phenomena of no-recirculation/recirculation is discussed. The change in the flow phenomenon due to a reversal of the direction of the net radial flow has also been studied.
