Özet:

 

The unsteady viscous flow produced by a sudden coincidence  of two axes while a disk and the fluid at infinity are initially  rotating with the same angular velocity about non-coincident axes is  examined.  The velocity field and the shear stress components on the  disk are found exactly with the use of the Laplace transform  technique.  In order to confirm the results obtained exactly, another  solution that is valid at small times is also obtained.  At the region  near the disk, it is observed that the projections of the rotation  centers of the fluid layers on the disk plane are in both the first  and the second quadrant for the given flow geometry.
