Numerical calculations by a finite-difference method have been made for a steady three-dimensional flow induced by a rotating disk with radial slits enclosed in a cylinder, and the results were compared with those for the nonslitted condition. The main conclusions obtained from the calculations are summarized as follows: (1)Considerable radial flows are generated inside the slits of the disk, resulting in a flow pattern quite different from that induced by a disk without slits and an increase of the momentum exchange. (2)With the increase in the Reynolds number the torque transmitted to the slitted disk is increased more due to the angular momentum exchange compared with that of the nonslitted disk.
