An approximate solution for flow between two disks rotating about distinct axes at different speeds. (English) Zbl 1141.76066
Summary: We study the flow of a linearly viscous fluid between two disks rotating about two distinct vertical axes. An approximate analytical solution is obtained for the rotations 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.
