Abstract
The flow of a linearly viscous fluid between two disks rotating about two distinct vertical axes is 
    studied. An approximate analytical solution is obtained by taking into account the case of rotation with 
    a small angular velocity difference. It is shown how the velocity components depend on the position, the 
    Reynolds number, the eccentricity, the ratio of angular speeds of the disks, and the parameters satisfying 
    the conditions u=0 and ν=0 in midplane.
