Analytical Solution to the Flow between Two Coaxial Rotating Disks Using HAM

The steady flow of a viscous, incompressible fluid between two infinite rotating coaxial disks is considered in this paper. An exact analytical solution to the problem is given by an effective analytical method called Homotopy Analysis Method (HAM).Three different cases such as one disk rotating with constant angular velocity while the other one is at rest, disks rotating in same as well as opposite sense with different angular velocities are considered and discussed for small Reynolds number.
