While two parallel disks are initially rotating with the same angular velocity about noncoincident axes, the axes are suddenly made coincident. The development of the flow is examined until the fluid rotates as a rigid body in the steadystate. The velocity field and the shear stress components on the disks are found exactly by a Fourier series solution. Furthermore, a series solution that converges rapidly at small times is obtained with the aid of the Laplace transform technique.
